He was detained yesterday on suspicion of being an accomplice of suspected attacker Anis Amri
A Tunisian man held in Germany over the Berlin Christmas market truck attack has been released.
He was detained yesterday on suspicion of being an accomplice of suspected attacker Anis Amri, who was killed in a shoot out with police in Italy last week.
It comes as German prosecutors say the weapon Amri fired in Milan was the same calibre as the one used in Berlin.
Prosecutors believe Amri was responsible for driving a truck into a Christmas market on December 19th, killing 12 people.
The bullets were the same .22 calibre as a bullet fired inside the cabin of the vehicle used in the attack, TheLocal.de reports, but investigations are continuing into whether they were fired from the same gun.
The truck's Polish driver Lukasz Urban was found dead in the passenger seat after the market attack.
He is believed to have died before the attack, although investigators are still attempting to establish the exact cause and time of death.
