A 20-year-old man has been arrested over the murder of mother-of-two Maria Rawlings.
The suspect was held on Sunday on suspicion of killing Ms Rawlings, 45, whose body was found in bushes in Little Heath, Romford on May 4.
Police believe she was attacked after leaving the King George Hospital in Goodmayes, Ilford, the previous evening, walking to Barley Lane in the direction of the A12.
A post-mortem examination found that she had been strangled and had suffered head injuries.
Detective Chief Inspector David Hillier, who is leading the murder investigation, said: “My thoughts remain with Maria’s family at this incredibly difficult time.
“I continue to appeal for anyone with information to contact police.”
