A 25-year-old suspect is assisting police with their investigation into a stabbing incident at the Trincity Mall car park on Friday night.
The TTPS says eyewitnesses say around 11:15, two men were in the car park in the vicinity of KFC when an altercation began.
During the brawl, one pulled out a knife from his pants pocket and dealt the other a single stab to his abdomen, causing injury.
The knife was taken away by a by-stander, and the injured man was taken to hospital where he remains in a stable but serious condition.
The suspect, from Bon Air West Arouca, was nabbed by police while attempting to make a report at the Arouca Police Station about the incident.
