Thai police have enrolled Santisuk to ape them on patrol in the Yala province, which is divided by Muslim insurgency.
It's a fur cop ... Santisuk keeps eye out
Locals resent being stopped at checkpoints. But when the uniformed pig-tailed macaque - his name means peaceful - is around, they ask for pictures with him.
Cpl Phromdao Yutthapol, who patrols with the monkey, five, said: "Other officers deal with annoyed drivers. With Santisuk the checkpoint is a happy place."
