Belgian authorities are continuing to detain a man previously convicted on terror-related charges who was speeding through the center of Brussels with a van loaded with two gas canisters late Thursday.

The prosecutor's office said Friday the man, identified only as M.A., was convicted last year and local media said he had sought to go fight in Syria. Once his identity became clear to police after he was stopped for running a red light, part of the center of Brussels was closed off during the evening rush hour.

A bomb squad found no detonator or explosives, and only one of the two gas canisters was full.
