Police have arrested an owner of a Brazilian nightclub where 231 people were killed in a blaze early Sunday that survivors said was set off by a musical group's pyrotechnics, a police official said Monday.

Relatives of victims from a fire that broke out at a nightclub weep over a coffin in Santa Maria, southern Brazil on Sunday.

Two members of the musical group also were arrested, and an arrest warrant was issued for another owner of the club, Kiss, said police official Michele Vimmerman. "There were three temporary detentions," Vimmermann said.
