Senior police are warning people in east Port of Spain to be cautious after a shooting in the area on Tuesday morning.
Police said they were called to Oxford Street at around 11 am after residents reported two groups of men were shooting at each other.
No one was killed or wounded during the gunfight and the men dispersed in different directions shortly afterwards.
Members of the Port of Spain Task Force and Besson Street police searched for the gunmen for several hours, but were unsuccessful.
Investigators said they suspect the shooting was related to an incident in Port of Spain last week.
One officer said the police warned residents and visiting tradesmen about visiting parts of east Port of Spain and Laventille, as they anticipate more shootings.
