A convicted killer serving an indeterminate sentence has been on the run for one week after escaping from Copenhagen’s Vestre Fængsel by climbing over the prison wall. Police continue their search and warn the public not to approach him.
One Week on the Run
Philip Denié Dahl Petersen has now been at large for seven days after his dramatic escape from Vestre Fængsel on the night of February 3 to 4. The 37-year-old left his cell, crossed the prison yard, and climbed over the outer wall around midnight. Copenhagen Police released an updated photo on the afternoon of February 11 to aid the public in identifying him.
Ongoing Police Investigation
Copenhagen Police confirmed they maintain an active search operation with ongoing investigative efforts. Vicepolitiinspektør Rene Gaardsvig stated that the original alert remains current and that authorities have received numerous tips from citizens. Despite this public engagement, the convicted killer remains free.
Authorities provided limited details about the investigation’s progress. They declined to specify the number of officers dedicated to the search or whether international cooperation has been established. The police emphasized that relevant investigative steps continue but offered no timeline for when Petersen might be apprehended.
What Police Are Asking
The public should immediately call 112 if they spot Petersen but must not attempt to approach or detain him themselves. He was last seen wearing a black beanie, black tight-fitting jacket, black long pants, and black shoes with white soles. Anyone with information can also contact police at 114.
The Criminal Background
Petersen received an indeterminate sentence known as forvaring for a fatal knife attack committed on June 8, 2022. This type of sentence is reserved for extremely dangerous offenders and allows for indefinite detention until psychiatric specialists and a judge determine the person can be safely released.
Double Stabbing at Copenhagen Bar
The conviction stems from an incident outside Sydvest Bodega in Copenhagen, where the convicted killer stabbed a former Hells Angels member three times in the upper body, causing his death. Petersen also stabbed another man multiple times in the legs that same night. Police arrested him the following day on June 9, 2022.
During his trial, Petersen insisted he acted in self-defense and maintained his innocence. However, the court considered his extensive criminal history, including four prior convictions for serious violence. Østre Landsret, Denmark’s high court, upheld the forvaring sentence in October 2025.
Danger Assessment
The National Board of Forensic Medicine assessed that the convicted killer would pose a danger to the lives, bodies, and health of others if released. This evaluation played a significant role in the court’s decision to impose the indeterminate sentence. Despite the serious nature of his crimes and the danger assessment, former Copenhagen Police detective chief Jens Møller suggests the public should not live in fear.
Understanding the Escape
The escape occurred at one of Denmark’s most secure facilities, raising questions about how such a breach was possible. Vestre Fængsel, built in the late 1800s, houses 535 prisoners primarily on remand awaiting trial. The facility features small cells measuring only seven to eight square meters.
Prison System Challenges
The convicted killer was awaiting transfer to Herstedvester Fængsel, the primary institution for forvaring inmates in Denmark. Capacity limitations prevented his immediate placement there despite his finalized sentence. This situation highlights broader challenges within the Danish prison system, where limited spaces can delay appropriate placements for high-risk offenders.
Lea Bryld, acting regional director for Fængselskreds Øst at Danmarks Fængsler, confirmed the escape is being taken seriously. However, prison authorities have withheld details about how the escape was discovered, whether any staff were involved or harmed, and what security measures were in place. Bryld stated that a full overview must be obtained before releasing such information.
Security Questions Remain
Multiple questions about the escape remain unanswered. Prison authorities have not disclosed whether security procedures will be reviewed or changed following the incident. The timing of the escape, occurring around midnight, and Petersen’s ability to traverse both the prison yard and scale the outer wall suggest potential gaps in surveillance or patrol coverage.
Expert Analysis of the Manhunt
Former Copenhagen Police vicepolitiinspektør and detective chief Jens Møller provided a perspective on why the convicted killer remains at large after seven days. He explained that hiding is significantly easier than being found, especially if someone remains stationary and avoids electronic devices that can be traced.
Investigation Priorities
Møller suggested that finding Petersen may not currently represent the highest priority for police resources. Law enforcement agencies must balance manhunt efforts with ongoing crime investigations and prevention work. This does not mean the search has been abandoned, but rather that it operates within the constraints of available personnel and competing demands.
The former detective chief believes police are likely contacting people from Petersen’s past, including former partners, hoping someone will provide information. Telephone surveillance may also be employed, though this requires knowing which numbers to monitor. As time passes, those harboring the convicted killer may grow weary of the burden and contact authorities.
Public Safety Perspective
Møller emphasized that Danes should not live in fear due to one escaped prisoner. He noted that convicted murderers are released from prison every year after serving their sentences, and numerous individuals previously sentenced to forvaring already live in society. The danger Petersen poses is most relevant to people he knows personally and might seek out.
The assessment that the convicted killer is dangerous serves primarily to warn those in potential conflict situations with him. Møller does not believe the victim of the attempted murder receives police protection, nor do witnesses who testified against Petersen. Standard practice involves informing such individuals so they can choose to stay elsewhere temporarily.
Life on the Run
The challenges of remaining hidden extend beyond evading police detection. Petersen cannot work, has no legitimate income, and cannot participate in normal society. This creates strain both for him and anyone providing shelter or assistance.
The Fugitive Reality
Møller described life on the run as miserable for everyone involved. The fugitive often becomes irritable and difficult due to confinement and inability to live normally. Those hiding such individuals face their own pressures, including legal jeopardy for harboring a fugitive and the practical difficulties of supporting someone who cannot be seen publicly.
These pressures frequently lead to resolution through voluntary surrender or tips from exhausted accomplices. The longer Petersen remains free, the more likely such factors will contribute to his recapture. However, if he has access to an isolated location and willing helpers, the manhunt could extend considerably longer.
