A 17-YEAR-old arrested under suspicion of attempted murder has been released without charge.

The teen was detained by Thames Valley Police following an incident in which a dog walker was stabbed in the stomach in Abingdon last week.

Following the boy's release, the force is now re-appealing for witnesses to come forward.

The offender put his left hand over the woman's mouth before stabbing her once and fleeing through the woods near Clifton Drive at around 10.30am on Thursday, July, 19.

The victim, who is in her 50s, has since been discharged from the John Radcliffe hospital.

After being arrested, the 17-year-old from Abingdon was released under investigation on Friday.

Police confirmed this afternoon that he has subsequently been released without further action.

The offender is described as white, aged in his late teens, approximately 5ft 10ins tall and of slim build.

He was wearing black turn-up denim shorts, a light grey top and white and black trainers. He was also wearing glasses.

Investigating officer Detective Inspector Ali Driver, of Force CID based at Abingdon, said: "I appreciate that this is a concerning incident, and we are investigating to identify and locate the offender.

"We have a scene-watch in place around the wooded area, and have stepped up patrols across Abingdon. Members of the public will notice an increased police presence including officers from our Mounted Section in the area.

"I am asking anybody who was in woodlands near Clifton Drive between 8am and midday on Thursday, whether they feel they saw anything significant or otherwise, to make contact with us.

"I am also appealing to anybody who thinks they recognise the person described to contact us.

"We will continue our high-visibility presence in the area, and you can approach and speak to any of our officers should you have any concerns.

"I would like to re-iterate, that incidents such as these are rare, and we are keeping an open mind about the motive for the assault.

"I am urging anybody who has any information, no matter how insignificant they believe it to be to contact us on 101, quoting URN 434 (19/7)."
