Another Tunisian Man Detained for Berlin Truck Attack

German authorities have detained another Tunisian man who may been involved in the Berlin Christmas truck attack, which killed 12 people and injured dozens of others.

24-year-old Tunisian migrant Anis Amri was killed in a shootout with Italian Police after a Europe-wide manhunt.

Authorities say the new suspect is a 40-year-old man who was not identified. Officials searched his phone and business.

The Guardian reports the man's telephone number was saved in Amri's cellphone. Prosecutors say further investigations indicate that he may have been involved in the attack.

ISIS has claimed responsibility for the attack.
