A 58-year-old man was repeatedly punched in the head by two men in a street attack.
The victim was attacked on the sea front in St Leonards in the early hours of Sunday January 8. Two men repeatedly punched him before running off towards Hastings pier.
Officers were called by paramedics to Grand Parade at around half midnight after the victim was found with head injuries.
The 58-year-old local man remains in a critical but stable condition.
Police are now appealing for witnesses to the assault.
Detective constable Gregory Montier said: "We are particularly interested in speaking with a man and woman who were seen walking along the lower promenade at around that time, as it's thought they may have seen something that could help us.
"If you were in the area and saw anything suspicious then please do get in touch."
Witnesses can email 101@sussex.pnn.police.uk or call 101 quoting reference 55 of 08/01.
