Thai police have enrolled Santisuk to ape them on patrol in the Yala province, which is divided by Muslim insurgency. 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 said: "Other officers deal with annoyed drivers. With Santisuk the checkpoint is a happy place."
