The DSI officials tried to arrest a Cambodian female vendor for allegedly selling imitated goods at the border town market 11 am, causing other vendors to become angry.
The vendors demanded the DSI officials to release the Cambodian woman but they refused and some tried to use their pistols to warn the Cambodians to back off but they became further angry.
The DSI officials tried to drive their six-wheel truck to flee from the vendors but they were blocked and many vendors threw bottles and rocks at the officials and truck.
Eventually, some 20 policemen and troops were dispatched to rescue them. During the rescue operation, a police officer was hit by a rock at his head.
The injured officials were rushed to a hospital.
The angry Cambodian vendors also damage a SUV vehicle of the DSI official and overturned it.
