A 16-year-old boy was among eight people held during an anti-crime patrol on Monday night in the Northern Division.
Police said the teen who is originally from Moruga was named as a suspect in the murder of 47-year-old Tunapuna man Lester Sookhai last December.
The teen was positively identified by a witness during an identification parade. Investigators are seeking advice from the Director of Public Prosecutions today.
At least two other men held during the exercise were also wanted in relation to murder.
Police said they received information on the location of the men after a high-speed chase earlier this month. While the men escaped during the chase, they crashed the car they were travelling in. In the car they found a cell phone which they used to locate the men.
