The families of two murdered girls took part in a march to mark the 20th anniversary of the unsolved case.

"Babes in the Wood" Karen Hadaway, nine, and Nicola Fellows, ten, were found strangled in Wild Park, Brighton, in 1986.

Labourer Russell Bishop was charged with the murders but acquitted at his trial at Lewes Crown Court in 1987. He was jailed for life in 1991 for kidnapping and sexually assaulting a seven-year-old girl from Brighton but has always denied killing Karen and Nicola.

Yesterday, friends and relatives of the girls marched more than three miles from Brighton's John Street police station to Wild Park clutching teddy bears and roses.

Among them were Nicola's mother Susan, her uncles, Nigel and Ian Heffron, and Karen's mother, Michelle Johnson.

They called on Sussex Police to re-examine the case. Mrs Johnson, 49, said: "All we want is justice for those two girls."
