Video: Fritzl planned cellar six years before abduction

A barman at a brothel frequented by Josef Fritzl, the Austrian man who imprisoned his own daughter in a dungeon under his house, has told how some of the prostitutes were so frightened by his perversions that they refused to accept him as a client.

He listed various extreme demands made by the retired electrical engineer, who liked to inflict pain on the women and asked them to act like corpses.

Christoph F, 38, worked at the Villa Ostende in Linz for six years and said that Mr Fritzl, a regular customer, was notorious for being "domineering" towards the staff.

"Ninety-five per cent of the guests are entirely normal, 3 per cent are slightly ‘derailed’, but Fritzl belonged to the last 2 per cent of extreme perverts, who are surely mentally deranged," Mr F told the Oesterreich newspaper.

He said that some of the prostitutes would refuse to go upstairs with him – "which was extremely rare in this business" – because of demands including sadism and "demanding that a girl should pretend to be a corpse".

Prostitution is legal in Austria, and the Villa Ostende charges its customers €150 an hour. Most of the prostitutes come from Eastern Europe and change every few weeks.

The barman said that Mr Fritzl, who kept his daughter Elisabeth captive in the cellar of the family home for 24 years and fathered seven children by her, was a longstanding customer renowned for his meanness.

"I was working there for six years and Fritzl would come regularly. I will never forget his stinginess," he said. "If he would consume drinks for €97 and would pay with a €100 bill – he would demand the €3 back.

"At the bar he was domineering. If he liked a girl he would order champagne for her, but after a short while he would start behaving like a headmaster with pupils and say things like ‘Sit straight!’ or ‘Don’t speak nonsense!’. Such behaviour is unusual in sex clubs."

In the aftermath of the Fritzl case, the Austrian Parliament is to discuss the introduction of more severe punishments for sex offenders.

The Nationalrat will discuss the case tomorrow, when MPs will debate a motion on whether to change the law to introduce tougher penalties for rapists, as well as to allow criminal records to be kept for a longer period of time.

Despite the fact that Mr Fritzl had a previous conviction for rape he was allowed to adopt, or become the foster parent, of three of the children claiming he was their grandfather. This is because Austrian law sees files on convictions for sex offences removed from the records after ten to 15 years.

Mr Fritzl served 18 months in prison for raping a 24-year-old nurse in Linz in 1967, when he was 32, after he threatened to kill her and put a knife on her throat. The judge at the time allegedly pronounced what was considered a lenient sentence because Mr Fritzl had four children.

The proposals from politicians from across the political spectrum to be discussed tomorrow range from introducing chemical or physical castration as punishment for serial sex offenders – an idea coming from the far Right – to stepping up efforts to prevent sex crimes and providing psychological counselling for sex offenders.

A proposal of the far-Right party, Alliance for the Future of Austria, to introduce regular check-ups for children to determine whether they were sexually abused has been rejected as an "absurdity" by other parties.
