A 33-year-old man arrested on suspicion of murder and then bailed is due to return to police today.
The unnamed suspect was held after the body of Aamena Hussain, 28, was found in a property in Grove Green Road, Leyton, on September 3.
The cause of death is yet to be established.
The Independent Police Complaints Commission is investigating the death due to previous contact between the police, the victim and the arrested man.
