Romanian prosecutors are questioning an owner of the nightclub where a fire killed more than 30 people and injured 180.

Anti-corruption prosecutors on Friday questioned Paul Gancea, one of the three owners of the Colectiv nightclub, where the fire broke out Friday night, the deadliest of its kind in Romania.

Gancea was responsible for securing permits for the club. He was detained Tuesday with the other two owners for "grave negligence and irresponsibility" and a "high level of social danger."

Agerpres news agency reported that prosecutors on Friday were taking documents from the district town hall where the club was located and the financial administration authorities.

The fire sparked mass protests and led to the resignation of Prime Minister Victor Ponta and his Cabinet on Wednesday.
