A Barataria man in his early thirties was detained for breaching the curfew on Monday night after he claimed he was put out by his girlfriend.
Police said members of the North Eastern Division on patrol between 8 pm and 11 pm found the man at Boundary Road Extension and asked him why he was out while the curfew was in effect.
Police said he told them he had an argument with his girlfriend, who put him out.
Officers said they suspected the man was lying and were wary of any such excuses. He was arrested.
During their patrol, police also found a shotgun and six rounds of 12-gauge ammunition in the area.
The exercise was led by ACP Belfon, Snr Supt Maharaj, Supt Ramjohn and ASP Parriman, with field operations by Sgt Quashie, Cpl Gordon, and PCs Mieres, Dass and Nanan.
