A Bangladeshi man has been treated for cuts and bruising after he was knocked unconscious in a racist attack.
Surrey Police said the 39-year-old had been walking along Kelsey Road, in Horley, with three other Bangladeshi men in the early hours of Friday.
They were approached by a group of men who asked if any of them had a lighter before racially insulting them.
The victim was then hit on the back of the head and knocked to the ground, where he was kicked and punched.
He was attacked by about 10 men, who were all described as white, and aged between 17 and 20.
The injured man told police he and his friends had earlier passed a group of about 15 men and women who were gathered on the grass in Court Lodge Road, near the junction with Manor Drive.
They were standing by two cars, one of which was described as blue.
Investigating officer Pc Dave Kirkwood said officers were not prepared to tolerate "hate crime".
"This was a cowardly attack and I would urge anyone who thinks they have any information about those involved to please come forward," he said.
