Quick action by the Emergency Response Patrol led to the arrest of a 29-year-old San Juan man after he reportedly robbed a man of a cellphone and a knife in St Augustine on Wednesday.
A police release said the 21-year-old victim was walking along Old Time Street, around 11 pm when two men approached and announced a robbery.
One of the men, armed with a gun, stood guard while the other stole a Samsung S6 cellphone and a black-handle flick knife, before running away.
The victim made a report to members of the Emergency Response Patrol, who were on mobile patrol in the area, and arrested one of the suspects a short distance away.
Both stolen items were recovered and the suspect taken to the St Joseph Police Station, pending charges.
Enquiries are continuing.
