Thames Valley Police is appealing for witnesses to an unprovoked assault on a profoundly deaf teenager.
The incident happened in the underpass of the V6 Grafton Street, at the junction with H8 Standing Way.
The 18-year-old victim was attacked by a man who punched him while another man filmed the incident on his mobile phone.
The victim suffered red marks to the side of his face and a lump under and above his eyebrow. He later suffered a panic attack and needed hospital treatment.
The incident happened between 9am and 9.30am last Friday.
PC Steve Cann, who is investigating the incident, said: “This unprovoked attack has left the victim very shaken and he is no longer confident to walk outside by himself.
“The offenders came from the Coffee Hall / Beanhill area and ran off towards the Bleak Hall area.
“I am keen to speak to any witnesses and anyone who may have seen the video of this incident.”
The first offender is white, 18-19 years-old, 5ft 7ins to 5ft 10ins, slim, with short black hair. He was wearing a black baseball cap, black hooded top, black tracksuit bottoms and black trainers, possibly Nike. He also carried a black bag with blue stitching.
The second man, who filmed the incident, is white, 18-19 years-old, 5ft 5ins to 5ft 7ins, slim, with short brown hair and a beard. He was wearing a white Adidas jumper, blue jeans and white trainers.
Anyone with any information about this incident should contact PC Cann via 0845 8 505 505.
