A man has suffered serious multiple stab wounds during an incident at The Boulevard in Crawley town centre.
Emergency services were called to the scene late on Saturday night. The victim, a 24 year old local man, was flown to hospital by air ambulance where his condition is critical. Police believe the suspects left the scene in a white vehicle and are appealing to anyone who may have seen it or the direction it was travelling in, to get in touch immediately.
Chief Inspector Rosie Ross said the possibility of the attack being drug related has not been ruled out.
