Police yesterday arrested six suspects accused of tying up and killing a security guard during the late-night robbery of a microfinance institution in Kandal province’s Ksach Kandal district, district military police commander Khem Makara said.

According to Makara, the alleged robbers walked away with the safe of a Microfinance Sathabana Ltd service branch after tying the arms and legs of guard Khoeun Sin, blindfolding him, gagging him with a lime and hitting him in the neck from behind.

Van Muth, a vice-CEO of the institution, said yesterday that the business hadn’t lost any money because the branch’s safe was emptied nightly. “But the thieves did not know that, that’s why they killed the victim.”
