A police constable was shot and killed last night in Chaguanas.

The deceased has been identified as PC Dale Mayers, who was last attached to the Arima police station.

Just after 10 p.m. Mayers was liming with his wife and a friend - who is also a licensed firearms holder - at Unique Bar along the Montrose Main Road in Chaguanas, when they were confronted by a lone gunman.

The man, dressed in all black, walked up and announced a hold-up.

However, as he looked away, Mayers pulled out his licensed firearm and shot at the suspect.

The suspect returned fire before turning and fleeing the scene.

Mayers was shot in the chest with the bullet exiting his left arm.

The police and paramedics were notified and Mayers was taken to the Chaguanas District Hospital.

However, he died while undergoing treatment at about 11:06 p.m. police sources said.

A team of officers from the Central Division and the Homicide Bureau responded to the report and made their way to the scene of the shooting.

A firearm was seized at the scene, the Express was told.

Investigators also observed a trail of blood running from the bar to the roadway and as a result, they determined that Mayers had shot and injured his attacker.

An all-points bulletin was issued, and checks were made at all nearby medical institutions.

Just before midnight, a 24-year-old man from Nelson Street in Port of Spain was dropped off at the Port of Spain General Hospital for gunshot wounds.

A vehicle drove onto the compound and the occupants opened fire on residents without warning before driving off.

They were all shot in the vicinity of Building 6.

Three other persons were also injured in this incident and have since been discharged.

Crime scene investigators recovered over 50 spent shells on the scene of the shooting including rounds of 7.62mm, 5.56mm, and 9mm.

While police recovered the vehicle used in the shooting that day, no one has been held in connection with the killing, the Express was told by police sources.

The two men got into a fight, during which the suspect shot Mitchell with his own firearm.

Anthony Hopkins of Quarry Road, Valencia, later surrendered to police in the presence of his attorney.

He was questioned, and later charged with Mitchell's murder.

This matter is currently before the courts.
