The suspect was apprehended without a fight, he did not resist. That usually means they have a message, they are seeking to be held as a hero.
That is not something a gang banger would to.
Sounds terror linked, and with it being Ramadan...
Feels like you may be right.
My impression is that he was surprised by the quick police response. Some of the people running out the theater ran into the police coming in. He apparently kicked in a back emergency door and his car was parked in back. So he was probably going to drive away and escape, but the police were just too fast and caught him in his car. Apparently he told the police he may have had explosives in his apartment. If he is connected to the before mentioned Pakistani terrorist group, they are experts in explosives.
