German authorities have released a Tunisian suspected of being involved in the attack on a Christmas market in Berlin last week. The man had been detained for alleged links to Anis Amri, the suspect who carried out attack. However prosecutors say they've confirmed the man wasn't in contact with Amri immediately prior to the rampage. Amri drove a truck into a crowded market, killing 12 people and injuring more than 50 others. Before the attack he released a video pledging allegiance to ISIS.
