Fritzl's secret dungeon to be welded shut after becoming teen party venue

London, Feb 15 (ANI): Josef Fritzl's underground cellar, where he sexually abused his daughter Elisabeth for 24 years, is to be sealed with a welded steel door by Austrian authorities - because teenagers have been partying in the secret dungeon.

The cellar has been violated in the months before contractors move in to demolish the house, reports the Daily Mail.

Old computers, smashed up chairs, a mattress, drug paraphernalia, smashed alcohol bottles and soiled clothes litter the warren of rooms that Fritzl constructed beneath the family home in Amstetten.

The illegal partygoers gained access to the cellar via an unlocked garage door to the house in Ybbstrasse in the Austrian town of Amstetten. (ANI)
