The Royal Newfoundland Constabulary has arrested a 35-year-old man after a stabbing in downtown St. John's Friday afternoon.

The incident occurred at Harbourside Park on Water Street.

The victim — a man in his early thirties — was stabbed in the neck area.

He was rushed to hospital around 3 p.m. Friday with what emergency responders say was a 15-centimetre laceration.

They say he lost a lot of blood — between one and one and a half litres — but managed to flag down emergency responders for help.

Police believe his injuries are serious but not life-threatening.

The RNC says it appears that the suspect and the victim do not know each other, and the incident is being treated as a random act.

Eyewitnesses say there were three or four people in the park at the time of the incident, and the victim was seen running up the stairs clutching his neck.

Police closed a portion of Water Street from Prescott Street to Cochrane Street. Harbour Drive was also closed from Clift’s-Baird’s Cove to Prescott Street.
