Sussex Police are appealing for witnesses after an unconscious man was found with a serious head injury in Eastbourne.
Police said officers were called to Moatcroft Road, at the junction with Upperton Road, just after midnight (00.01am) on Monday (August 30) after a 42-year-old man was found in the street.
He was taken to the Royal Sussex County Hospital in Brighton, where he remains in a critical but stable condition, said police.
Police investigating the matter believe the man was involved in an altercation, potentially with three other men, earlier in the night.
