BERLIN — German authorities on Sunday issued a wanted notice for a fugitive suspect in the van ramming near Berlin’s Pride festival that left one person dead and injured at least 16 others.

Police and prosecutors asked for help in finding the 21-year-old, whom they identified as Abdul B.

They said he is believed to have injured several people with a moving vehicle, and that one or more people apparently then left that vehicle. Several people were also apparently stabbed, they added.

Sunday’s notice warned the public to avoid “direct contact” with the suspect, saying that he may be armed and dangerous.

Police had said earlier that they had identified a suspect who has ties to Islamic groups in the German capital.

“The suspect is known to police. He is known to us as a member of Islamic circles here in Berlin, and our search for this person is proceeding at full speed,” police spokesperson Florian Nath said.

Nath added that “we still have no information whatsoever regarding his specific motives, the exact sequence of events, or his role in the crime itself.”
