A live German television model casting show featuring model Heidi Klum was abandoned after a woman called in a bomb threat.

TV channel ProSieben abruptly yanked "Germany's next Topmodel" off the air Thursday night, initially citing "technical problems."

Police said Friday that an anonymous caller had phoned in a bomb threat to the venue, the SAP Arena in the southwestern city of Mannheim. Some 8,500 people were evacuated from the arena.

Officials then found a suspect suitcase near a changing room, but it turned out to contain nothing dangerous and the owner was quickly found. No other suspicious objects were found.

Klum tweeted: "Dear GNT fans, unfortunately the evening didn't end the way I wanted! Safety comes first!"
