German police release only suspect held in custody for Berlin attacks
The prosecutor`s office said the investigation "did not yield any urgent suspicion" against the man authorities thought was part of a possible terror attack.
Authorities lacked sufficient evidence to prove the man was sitting in the truck at the time of the attack.
Germany`s police is on "high alert" and assumes the armed-perpetrator is "still at large."
On Monday, a semi-truck mowed down crowds at a holiday market festival, killing 12 people while injuring 48 more.
