Authorities in Preah Sihanouk province’s Prey Nop district on Tuesday stopped the filling-in of a canal that serves as water drainage.

Prey Nop district’s administration chief Prom Bunny said on Tuesday that three trucks, a bulldozer and a roller were impounded in the operation.

Bunny said officials went to inspect the site on Wednesday and ordered the owner to dredge the soil out of the canal.

“We don’t know whether the owner had received permission, but we have not permitted any filling-in of the canal or lake. The owner would need to solve the matter, otherwise we will take legal action,” he said.
