Two sex attackers could be on the loose in Oxford, police warned today.

Officers now believe four attacks in the Southfield Road area and a sexual assault in Westbury Crescent are not linked.

Police have today issued a new e-fit of the man they believe could be responsible for the attacks in Southfield Road over the past 12 days.

A previous picture released by officers relates to Sunday’s unrelated attack in Cowley.

Det Insp Simon Morton said: “Our initial feelings after the sexual assault in Westbury Crescent, was that the incident was connected to the previous assaults in Southfield Road.

“However, certain details have come to light that has led us to believe that the attacker in this incident is different from the man who carried out the previous attacks.

“We have gone back to the victims from the Southfield Road assaults and spoken to them at length, which has led to this new E-fit being created.

“We hope that by releasing this new image, someone out there might recognise this man and come forward and help us with our investigation.”

Witnesses should call police on 08458 505505 or Crimestoppers anonymously on 0800 555111.
