Lerum 2020: 16-year-old moped rider died after police followed – officer acquitted

Alexander Storåker, 16, died in Lerum on May 12, 2020, when a plainclothes police patrol pursued the cross moped. The police officer was charged with causing another person's death and misconduct but was acquitted. The case highlights the regulations for the pursuit of unprotected vehicles.

Summary: On May 12, 2020, 16-year-old Alexander Storåker died in Lerum after a plainclothes police patrol attempted to stop the dirt bike he was riding with a friend. The moped turned onto a smaller road/path and crashed; Alexander succumbed to his injuries. The police officer driving the car was charged with involuntary manslaughter and misconduct. Alingsås District Court acquitted him on November 4, 2021 (case B 835-20). The verdict was upheld in higher courts; the Supreme Court did not grant leave to appeal.

Motverket presents the public legal status and procedural issues the case left behind. We do not assign blame beyond the courts' examination. The case is relevant again when police vehicles and young individuals on two-wheeled vehicles meet in traffic – most recently in Nybro on August 2, 2026, where two boys on an electric scooter are in intensive care after a collision with a police bus during a check. For how common police vehicle accidents are during emergency responses, see the VTI review.

What Happened According to Public Sources

According to sources including Uppdrag granskning, SVT, and the district court's summary, local police had received complaints about modified mopeds. A plainclothes patrol from Alingsås encountered the moped. When stopping it failed, the police car followed; lights and siren were activated. The moped turned onto a smaller road in a residential area and crashed – media reports mention a concrete barrier and a lamppost. Alexander died from his injuries.

The exact speed, distance between the vehicles, and whether the event legally constituted a "pursuit" or a brief stop attempt were contentious issues in the trial. Witnesses described a chase; the police officer described a stop attempt at low speed. The district court found that the event was very brief and that there were no independent witnesses to the entire sequence of events.

What the District Court Actually Examined

The prosecutor at the Special Prosecutor's Office argued that the police officer violated the principles of necessity and proportionality in the Police Act and regulations on pursuit, and that the actions agitated or stressed the driver, causing loss of control.

Alingsås District Court stated in its press release that the prosecutor could not prove that a pursuit occurred in violation of law or regulations, nor that the police officer caused the crash by being close to the moped as alleged. The charges were dismissed. The court was unanimous.

It is a matter of evidence, not a statement that the incident was harmless. The court says that criminal liability is not proven – not that the family lacks reason to demand clarity on procedures.

Regulations on Pursuit of Mopeds

In the Police Authority's regulations, it has been highlighted in media coverage that pursuit of two-wheeled motor vehicles or vehicles without protective bodywork is only allowed if exceptional reasons exist. Suspicion of a modified moped or reckless driving has been raised in public debate as insufficient compared to serious crime. The prosecution's case partly relied on the absence of such reasons.

After the accident, local police leadership stated that they practically stopped stopping moped riders for a period due to uncertainty about where the line is drawn when the vehicle tries to evade. Regardless of how the verdict is interpreted, it highlights a regulatory conflict: the control mission meets unprotected young road users in environments where stops and pursuits quickly become life-threatening.

What the Case Leaves Behind

Documentation and Witnesses. When the event lasts seconds, cameras, radio traffic, and independent witnesses matter more than reconstructions after the fact.
Exceptional Reasons. If the regulations set a high threshold for pursuing a moped, both training and local practice must reflect that – and be openly reported when something goes wrong.
Independent Review. Prosecution via the Special Prosecutor's Office and acquittal in court are parts of the same rule of law: suspicions are tested, but acquittal does not necessarily close the political and supervisory question about procedures.
The Family's Right to Answers. Public reports describe that the parents have fought for redress and feedback from the authority. It is a separate legal security issue, distinct from the evidentiary requirements of criminal law.

The Connection to Nybro 2026

Nybro and Lerum are different incidents, vehicles, and legal situations. What they have in common is that young people on unprotected vehicles encounter the police's stop or control ambition, that injuries can become catastrophic in seconds, and that the public must wait for a special investigation to get an independent picture. Motverket publishes the Lerum case as legal background – not as evidence of guilt in Nybro.

Conclusion

Alexander Storåker died at 16 years old after police followed the moped in Lerum. The police officer was acquitted. The legal outcome is clear; the public question remains: how the police may and should act against unprotected young road users when they do not stop, and how quickly and transparently it is reported when someone dies or is seriously injured. This question is relevant again after the collision in Nybro.
