The only suspect held after Monday’s deadly lorry attack on a Berlin Christmas market has been released, prosecutors say.
They say they do not have sufficient evidence to pursue the case against the suspect.
The man, named as Naved B, a 23-year-old asylum seeker from Pakistan, was arrested after he was seen leaving the scene of the attack, reports The Guardian UK.
However, police expressed doubts about whether the man they had arrested was indeed the person responsible for the attack.
According to the BBC, the man earlier denied any involvement. He was captured in a park after reportedly fleeing the scene.
The lorry attack left 12 people dead and nearly 50 injured.
Michael Behrendt, a reporter with Die Welt, who first reported police doubts that they had the perpetrator, said one main reason the police were fairly certain early on they had not got the right man was the fact that he had no blood traces on him when he was apprehended immediately after the attack, whereas the truck cab was full of blood.
The release of Naved B from custody may mean the driver of the truck is still at large, with fears that police do not know who is responsible for the attack.
