Following the arrest on Monday of two security guards at Siem Reap town’s Lucky Mall in connection with an ATM heist, police yesterday revealed that two more members of staff have been identified as suspects.

The theft, which took place in the early hours of Monday morning, saw the contents of two of the mall’s ATMs – belonging to ANZ Royal and Canadia Bank – emptied.

While two security guards were arrested and detained for questioning, Siem Reap province deputy police chief Thorng Sokun said his forces are still “tracking two other suspects who work in the mall”.

“I cannot say anything more right now as the investigation is still ongoing,” he added.

Despite the investigation so far pointing towards an inside job, Sokun said, both security guards have claimed innocence.

“They said they knew nothing as they were sleeping during that time,” he said, adding that both were sent to the provincial court yesterday afternoon for further questioning.

Provincial prosecutor Kert Vanna Reth said he had no information about the case.
