The list of crimes carried out by Co Laois man Robert Howard (61) over five decades was revealed today after a court order was lifted.
1944 -Howard is born Wolfhill, Co Laois
1964 -Howard commits his first sexual offence, attempting to rape a six-year-old girl in London. He broke into the child's bedroom pretending to be a doctor and ordered her to undress.
Howard failed to have sex with her but performed a vile sex act, injuring the girl.
He was captured by police after returning to the house a week later. Sentenced just before his 21st birthday, he served just nine days in borstal for the crime.
March 1969 -Howard breaks into a house in north east England and tries to rape a young woman. She escaped his clutches and ran into the back garden, but was chased and knocked to the ground by Howard who then tried to strangle her.
He fled when neighbours were alerted by her screams. He was sentenced to six years in jail for attempted rape and aggravated burglary.
March 1974 -Jailed for 10 years after being convicted in Cork of raping a 58-year-old woman. The victim was asleep in bed when Howard broke in, gagged and bound her with a sheet and then subjected her to a five-hour ordeal of sexual assaults as well as being forced hand over money.
1983 -Howard marries, but the relationship lasts only three years.
1988 -Sentenced to 15 months in prison for larceny offences in Dublin.
1990 -Howard moves to Northern Ireland after being released from Mountjoy Prison in Dublin. Spends time at an alcoholism rehabilitation unit in Newry, Co Down, before going on to Derry.
1991 -The predator arrived in Castlederg, Co Tyrone, moving into a flat on the town's Main Street.
1993 -He lured a 16-year-old girl to the flat. She alleged that during a two-day nightmare Howard drugged, stripped and repeatedly raped her while a noose was tied round her neck.
Every time she refused, he tightened the rope round her throat and threatened to kill her unless she followed his orders, the girl claimed. His victim only managed to escape by breaking out through an upstairs bathroom window.
He claimed the teenager consented and was later convicted of the lesser charge of having unlawful sex with a girl under 17. Howard was given a three-year sentence, suspended for five years.
August 13, 1994 -While still charged with rape, Howard drove Arlene Arkinson to the seaside town of Bundoran, Co Donegal, for drinks with his girlfriend's daughter and her boyfriend.
