A man who plied young girl callers to his home with drink then sexually abused them has been jailed for 10 years.
Andrew Stephen Brown used the youngsters as a sexual substitute for his estranged wife, Durham Crown Court heard.
Brown carried out the abuse at houses he occupied in Jarrow and at a house at Gilesgate, Durham City.
The court heard one of his victims has since suffered a nervous breakdown as a result of her ordeal.
Prosecutor Amanda Rippon said: "This man is a serial sex abuser of young girls who was willing to carry on the abuse even when he may have been observed.
"He never thought the victims would complain, and if they did, he thought they would not be believed."
The court heard one of his victims was forced to carry out a sex act with Brown about 200 times during a five-year ordeal.
Most of his victims were between 11 and 16 years old, and the offences took place between 2003 and 2008.
A victim complained in 2007, but Brown carried on abusing girls after he was arrested and bailed.
The court heard he was a heavy drinker and when he was living in Jarrow, his house became a magnet for young people who knew there were no rules there, and they could get drink.
Brown, 44, of no fixed abode, admitted five charges of sexual assault and two charges of sexual penetration of girls aged both under and over 13 years.
Tom Moran, defending, said: ''These were dreadful offences, but he co-operated with the police and has admitted his guilt.
"He was abused in the distant past, and while it might be thought that would make him determined not to make others suffer as he has done, sadly that has proved not to be the case."
Judge Guy Whitburn, QC, jailed Brown for 10 years and banned him from ever working or living with children.
The judge told him: "I'm not going to waste too many words on you, you know full well what you have done."
Brown's licence period on release was extended from five years to 12 years.
He must sign the Sex Offenders' Register for life.
