Yorkshire Ripper victim Tracy Browne will reveal on TV how she survived a hammer attack at his hands.
Tracy was a 14-year-old schoolgirl when she was attacked by Peter Sutcliffe as she walked home on a lonely farm road at Silsden in August, 1975.
On a Channel Five documentary, due to be shown tonight, Tracy will tell how the Bradford lorry driver struck up a conversation with her before hitting her five times in the head with a hammer.
She survived because the Ripper was disturbed by an approaching car. He dumped her over a fence and ran away, leaving her bleeding and barely conscious.
Sutcliffe, who was convicted of murdering 13 women and trying to kill seven more in a five-year reign of terror across the North in the 1970s and 1980s, did not confess to the attack on Tracy until 1992.
She describes her ordeal in Left For Dead By The Yorkshire Ripper, a new documentary on Sutcliffe told through the experience of his victims who got away.
