Images released in hunt for killer
Detectives hunting a killer and serial rapist have released CCTV images of a suspect.
The murder of Michelle Samaraweera, 35, in Walthamstow, east London, in May last year, has been linked to a string of other sex attacks in the area.
Police published surveillance camera pictures of a man they want to speak to in connection with the crimes. He is shown going into the Somerfield supermarket in Markhouse Road, Walthamstow, on the night of the murder after Ms Samaraweera had already entered the shop.
Ms Samaraweera's body was discovered in a small park off Queens Road in Walthamstow in the early hours of May 30 2009. She had been raped and strangled.
Detective Chief Inspector Stewart Hill said: "Michelle was callously murdered as she returned to her boyfriend's address after stopping at a local supermarket.
"We have been trying to trace a man who entered the shop on the same night as Michelle and we're keen to speak to anyone who can help us identify him. Due to the clarity of the pictures we're confident someone will know him and know his current whereabouts."
Detectives have DNA linking the killer to three other serious sexual assaults in the Walthamstow area, and they believe another two attacks on women may also be connected.
The suspect is described as being of Asian appearance and aged between 30 and 45.
Police arrested five men in connection with the inquiry last year but they were all later released without charge and no further action will be taken against them.
