A CALL for another investigation into the Yorkshire Ripper case has been dismissed.
The son of one of the Yorkshire Ripper's victims has said he fears his mother could have been killed by someone else.
Richard McCann said there was doubt over Peter Sutcliffe's confession and added he was concerned about a "copycat" theory.
But the idea was dismissed by one of the top detectives who worked on the case.
Former Det Supt Dick Holland, of Huddersfield, who was number two on the inquiry, said there was no need for a fresh look at the case.
He said: "We saw no need to consider any other person for the attempted murders or murders with which Peter Sutcliffe was charged.
"I knew of no reason why any other person should have come into the inquiry".
Mr Holland's comments came after Mr McCann, whose mother Wilma is thought to be Sutcliffe's first victim, claimed that children of two other victims were also concerned.
Sutcliffe was jailed in 1981 and given 20 life sentences for killing 13 women and attempting to kill seven more.
