A SEX attacker remains at large after an initial suspect was released without charge.

Two women were attacked just hours apart, first in Wokingham and then in Bracknell, with the attacker in both cases grabbing the women, pulling them to the ground and trying to rip off their clothes.

The first woman was saved after her dog became ‘aggressive’ and scared the attacker off.

Just hours later, a 25-year-old woman was walking in Coopers Hill, Bracknell when a man grabbed her, forced her into a bush and tried to rip off her clothes.

The woman showed ‘great bravery’, officers said, as she managed to fight him off.

A 28-year-old man from Bracknell was arrested on suspicion of attempted rape in connection with the first incident, but was released without charge.

Police are still appealing for witnesses and have released an artist sketch to find the offender.

He is described as having tanned skin, dark hair and is clean shaven.

He may be aged in his thirties and is about 5ft 7ins tall.

He was wearing a black hooded top and black or navy jogging bottoms.

Detective inspector Jason Liles said: “I would ask members of the public in this area to be extra vigilant and to contact police if they see anything which they think could be suspicious."

Officers are continuing to investigate whether the Winnersh incident is linked to a sexual assault which occurred in Coopers Hill, Bracknell.

Investigating officer Detective Inspector Jon Groenen, of Newbury Force CID, said: “I would like to speak to anyone who recognises the man show in the image, or anyone who has any information which could help us to identify him.

“We are continuing to investigate both incidents and the possibility that they could be linked.

“If you have any information which you think could help our investigation, please call the Thames Valley Police non-emergency number on 101.”
