German authorities suspect that the man who drove a truck through a crowded market in Berlin, killing 12 people and injuring almost 50 others, is 24-year-old Anis Amri, multiple media outlets reported on Wednesday.

Here's what we know about the suspect:

• Amri, a Tunisian asylum seeker, had previously been identified as a potential terror threat by German officials, according to the Associated Press.
• A German state minister told CNN Amri's asylum request was denied, and he was scheduled for deportation.

• Amri was named a suspect shortly after investigators discovered his identification papers in the truck at the scene of the attack. He has six known aliases, the AP reported.
• In a public notice released Wednesday, authorities offered $105,000 for his arrest, warning that he is likely "dangerous and armed."

• Germany is treating the attack as an act of terrorism. The Islamic State has claimed responsibility, describing Amri as a "soldier" who acted "in response to calls to target nationals of the coalition countries."
