Three people were arrested on suspicion of assault after a man was attacked in Regency Square, Brighton, at around 1.15am today (Tuesday 29 June).
Detective Sergeant Chris Sherwell said: “The victim flagged down police officers driving along the seafront and was driven round the area where he identified the three suspects in Western Road within eight minutes of the assault taking place.
“This was an unprovoked attack on a man who was trying to help a woman lying in the street.
“We are keen to speak to any witnesses.”
The victim, 42, walked from Preston Street to the junction of Regency Square, where he was attacked by two white men.
He was chased by them then assaulted in the street and within the square itself by the woman and the two men before they ran off away from the seafront.
The victim suffered a broken cheekbone.
He was taken to the Royal Sussex County Hospital in Brighton and has since been discharged.
Two men from Hove, aged 20 and 33, and an 18-year-old woman from Portslade were been arrested on suspicion of GBH with intent.
A spokesman for Sussex Police asked witnesses to call 0845 6070999 or Crimestoppers anonymously on 0800 555111.
