Thekilling of Lisa refers to the violent death inDuivendrecht, Netherlands of a 17-year-old girl named Lisa from nearbyAbcoude (as she was a minor at the material time, her surname has been withheld for legal reasons). She was attacked by an illegal migrant from Nigeria, a suspect in several sexual assault cases,[2] in the early morning hours of 20 August 2025, while cycling home after a night out inAmsterdam. The case received widespread national attention and sparked public debate around women's safety in public spaces at night and the country's handling of illegal immigration.
In the early hours of 20 August 2025, Lisa was cycling from the Leidseplein in Amsterdam to her home in Abcoude. At around 03:30, she was last seen riding a bicycle and traveling along the Holterbergweg in Duivendrecht. Around that time, she called emergency services during an attack by a man on a bicycle. Police found her body at approximately 04:15 along the water's edge on Holterbergweg.[3]
Lisa's emergency call was confirmed by police, though they did not disclose details of the conversation. Surveillance footage captured much of her route, except for the final seven minutes. Investigators requested witnesses and dashcam footage from the area, especially from individuals in three specific vehicles seen between 04:10 and 04:30 on Holterbergweg: a scooter, a light-colored van, and a Biro vehicle.[3]
A suspect was arrested in a temporary asylum shelter inAmsterdam-Zuidoost the day after the killing. Initially, he was detained for a separate sexual assault case onWeesperzijde. The following day, suspicions were expanded to include involvement in Lisa's death. As of 29 August the identity of the man remained unclear, with conflicting reports regarding his age and nationality.[4]
The suspect was expected to appear before the Raadkamer (Judicial Chamber) on Monday, a procedural hearing regarding potential extension of pre-trial detention. The prosecution stated that more details would likely be revealed once facts had been firmly established.[4]
Lisa's death sparked a national outcry and reignited discussions about women's safety in public spaces, especially at night. Activist groupDolle Mina organised nationwide protest bike rides in at least 19 cities, including Amsterdam, Rotterdam, and Groningen. The events were aimed at reclaiming unsafe routes and drawing attention to societal responsibility for safety, particularly for women.[5]
OnLeidseplein in Amsterdam, a digital billboard displayed the message "Wij eisen de nacht op" ("We reclaim the night") in memory of Lisa. The campaign encouraged broader conversations about shifting responsibility for safety from potential victims to society at large.[5]
In the days following the incident, over 85,000 people downloaded the Dutch emergency app 112NL. The app, which allows for silent communication with emergency services and automatic location sharing, saw a 20% increase in downloads, reflecting heightened public concern over safety.[6]
In Lisa's hometown ofBaarn, a local initiative was launched to improve nighttime safety for cyclists. A community-driven app is in development to provide better protection for night cyclists, allowing users to share routes, alert each other, and connect in case of emergency.[7]
Lisa's family, through the organisation Namens de Familie, expressed deep grief and gratitude for the national support. They requested privacy to mourn the loss of their daughter and highlighted the widespread solidarity from friends, neighbors, and the broader community.[3]
According to Marieke Liem, professor of safety and interventions atLeiden University, Lisa's death was highly unusual. Her research covering the period from 2015 to 2024 showed no other known cases in the Netherlands in which a minor girl was killed by an unknown assailant. Typically, perpetrators in cases of female homicide are known to the victim, such as partners or family members.[3]
