The white man was beaten and hit several times with a bottle by a gang of youths at about 1.30am on Saturday.

He was approached by a gang of between ten and 15 Asian youths who surrounded him and shouted racial abuse before repeatedly punching the man in the face.

Det Con Elaine Bartlett, Investigating Officer, said: "This was a particularly brutal and callous attack on a lone man.

"Thankfully this type of incident is very rare in Aylesbury which is why we are hoping to speak with anyone who may have seen the group as they left the park.

"Even if you went past in a taxi on your way home from a night out, what you saw may be vital in helping us track those responsible."

The man lost his footing and fell to the ground as he took a step back to avoid his attackers.

Whilst on the ground he was struck with a glass bottle over the head and face several times before the youths made off.

He was taken to Stoke Mandeville Hosptial for treatment to cuts and swelling to his head and face.

Anyone with information about the incident is being asked to contact Det Con Bartlett at Aylesbury CID on 08458 505505 or by contacting the Crimestoppers charity anonymously on 0800 555111.
