On 31 July 2021, a police officer shot a man armed with a knife, who later succumbed to his injuries.

An investigation was launched following the shooting, but on Wednesday Diekirch court ruled that the act had occurred in self-defence. All charges against the police officer were dropped as a result.

The court upheld the officer's account of self-defence in the face of "the aggression to which he was exposed", according to the prosecution's statement. They went on to confirm the officer's reaction was necessary and proportionate to the danger posed by the victim.

In this instance, the victim had threatened a motorist in Hosingen with a knife in order to steal the vehicle. He was later embroiled in a police chase in Ettelbruck, where he attempted to attack the officers who stopped him. It was at this point that the police officer in question used his service weapon to fire at the attacker, who later succumbed to his injuries in hospital.
