Police fear Royal Docks sex attacker will strike again

More images have been released of that latest attack.

It took place on November 9 when a woman was followed into her apartment block in Seagull Lane, E16, just before 1am.

While waiting for the elevator she was grabbed from behind and sexually assaulted. She confronted the man, who told her to be quiet and assaulted her again.

She pushed him away and escaped into the lift.

It followed two incidents which took place in 2011, six months apart.

Police are eager to catch the man and have released images of the most recent attack.

DC Tina Dilworth of the Met's Sapphire Command said: "The man responsible for these assaults must be stopped before he goes on to commit another offence.

"If you recognize either man shown in these images, please contact my team immediately."

The suspect is of Asian appearance, around 5ft 7ins tall and of medium build.

He first struck on June 22, 2011, at about 11.45pm.

Echoing the most recent attack, he followed a 51-year-old woman into her Seagull Lane apartment block near Royal Victoria DLR station.

After being confronted by the woman, he became aggressive, grabbed her arms and sexually assaulted her.

He ran off when she screamed for help.

The second incident took place on October 14 at 8.30pm. He tailgated a 22-year-old woman into her apartment block in Western Gateway.

He followed her into the lift, sexually assaulted her and said he would kill her if she told anyone. He then assaulted her again in the corridor.

The victim managed to raise the alarm with residents and the suspect ran off.

Last year police also released an image of a man who was seen with the suspect. He is believed to an associate.

A 25-year-old man was arrested in October 2011 in connection with the attacks but was released with no further action.
