A 61-year-old retired police sergeant is in police custody after he shot and wounded a special reserve police (SRP) constable who tried to quell an argument with another customer in Sangre Grande on Monday.
Police said the SRP was moonlighting as security at the One Plus One supermarket at Foster Road, Sangre Grande at around 3.20 pm when he heard an argument between the retired policeman and a customer.
As he attempted to calm both men down, the SRP got into an argument with the retired policeman who took out his licenced pistol and shot him in both legs.
The retired policeman was subdued and police were called.
Police took the wounded SRP to the Sangre Grande hospital where he was treated. They seized a Glock pistol with eight rounds of ammunition.
Investigators said the man was last assigned to the Northern Division.
Sangre Grande police are continuing enquiries.
