Man admits rapes from 25 years ago after new DNA link

A sex attacker who raped two women almost 25 years ago has admitted the offences after a "cold" case investigation.

John Walker assaulted a 25-year-old woman near Wembley Tube station in 1987, then 18 months later struck again. On that occasion, he grabbed a vulnerable teenager from a platform at
Marlow railway station, and forced her into a workman's hut where he attacked her.

Walker, 51, of Cotterells, Hemel Hempstead, remained undetected until October last year when a team of police re-opening "cold" cases found the father-of-two's DNA matched samples taken from both women in the Eighties.

Yesterday Walker admitted at Oxford crown court two indecent assaults and a rape of a woman in 1987, and the rape and indecent assault of an 18-year-old in 1989.

When police swooped on Walker they found two bottles of chloroform and images of young girls in his van.

Sentencing was adjourned until February 10.
