A security guard shot and killed a suspected thief on the compound of a quarry in Central Trinidad on Monday.

Police said shortly before 5 p.m., two armed, masked men attacked a supervisor at a ’sand pit’ located on the Caparo Valley Road.

A security guard shot one of the men, who later died at hospital. The second man escaped with nothing.

Police said they recovered a gun and ammunition. The dead man remained unidentified last evening.

Sgt Wayne Lawrence is spearheading investigations.
