Police are investigating a robbery that occurred at DHL's El Socorro building on Wednesday night.
Police say two men walked onto the Chanka Trace compound around 10:30 pm and tied up the security guard on duty.
Guardian Media understands the men then walked behind the building to the loading bay where they ordered four workers to lie on the ground. They then proceeded to tie up those workers.
Reports are the bandits frisked the employees and stole their cellphones and cash, before searching the loading bay for valuables to steal.
They made their escape afterwards.
Police say one of the workers managed to free himself and called for help.
Investigations are ongoing.
