Police have urged women walking alone late at night to be vigilant after two rapes.

In the first incident, a 35-year-old woman was walking home in a residential street in Plaistow South, Newham, at around 2.40am when she was approached from behind by a man.

The attacker raped her and also stole property.

Five days later, a 31-year-old woman was raped and robbed by a man who approached her in Amethyst Road, Waltham Forest, on Saturday at 4.20am.

Detectives from the Met's North East Command Unit have linked the attacks.

They have released an image of a man they are keen to trace, which was captured on a bus in Plaistow shortly before the first incident.

Detective Superintendent Andrew Packer said: "These incidents have been deeply traumatic for the victims, who are being supported by specialist officers.

"My teams are completing a detailed review of all the facts available so far. In addition to a dedicated investigation team we have extra patrols in the area to provide reassurance and these officers are actively seeking to arrest this suspect.

“Please have a good look at this photo and let my officers know if you have any idea who this man is.

“I would advise any women walking alone at night to remain vigilant, to be mindful of their surroundings, and to keep family and friends informed of where they may be going. If you see anything you think is suspicious, do not hesitate - call 999 immediately."

Anyone who can identify the man should call the investigation team on 07881 330951.

They can also call 101, tweet @MetCC quoting CAD 777/1 July or contact Crimestoppers anonymously on 0800 555 111.
