He said: “We would especially like to speak to a man who helped one of the victims when she was distressed at the bottom of Cold Bath Road, and also a woman who was waiting at the bus stop in the area of Walkers Passage who may have seen what happened.
"If anyone has any information concerning the incidents, or has concerns that they may have been followed, then please call 101.”
