Facebook appeal over Mohammed Bourner attack in Bexhill
Police are using Facebook to try to find the person responsible for a serious assault on a Sussex teenager three weeks ago.
Mohammed Bourner has been transferred from Hurstwood Park Neurological Centre to King's College in London, where he remains in a critical condition.
The 15-year-old, known as Mo, was punched in De La Warr Parade, just before midnight on 28 October.
He had been at a party on the seafront at Glyne Gap with three friends.
Sussex Police has set up a private Facebook account to encourage people to post information confidentially.
They have also released CCTV footage of two girls and two boys in MJ'Z bar in Bexhill at around 01:00 GMT on 29 October.
Police say the four, who all appear to know each other, may have vital information on the assault.
One girl was blonde, the other was brunette, while one of the boys was wearing a checked shirt and one had dark rimmed spectacles.
