Thames Valley Police is appealing for witnesses to a robbery in Slough.
The victim, a man in his forties, was walking in High Street in Chalvey and went behind the YMCA building towards the Chalvey recreation ground at around 4am on Sunday (9/9).
Two men approached the victim and punched and kicked him until he was unconscious. The men moved the victim behind some bushes between the YMCA and Chalvey recreation ground and stole his phone and other personal items.
The first offender was wearing a grey hooded jumper with lines down the arms which looked like rips from a distance.
The second offender was riding a bike.
It is believed that the offenders went in to the BP Fuel Station on High Street Chalvey following the assault.
The victim suffered a broken jaw and facial bruising and was treated in hospital, where he remains.
Investigating officer, PC Jacqueline Barnes, of the Investigation Hub in Slough, said: “This was a very serious assault and I would like to hear from anyone who may have information about this incident.
“The victim is still recovering in hospital and his injuries could have been even worse as he was left unconscious without medical help.
“If you do have information about this incident, please contact the 24-hour police call centre on 101 or you can make a report online here quoting the reference number ‘43180275703’.
“You can also make a report anonymously by calling Crimestoppers on 0800 555 111.”
