Tri said he was informed by local officials that several organisers had sought permission to hold concerts by Myanmar entertainers for workers from Myanmar in several areas in Phuket, including Muang, Thalang sand Krathu districts.
He said the officials were told that some 10,000 tickets had been sold.
But he informed the officials that the concerts could not be approved.
Moreover, the Phuket Provincial Administration put up announcements at various places, telling workers from Myanmar and Cambodia to return to their shelters before 8pm.
Tri said that if workers from neighbouring countries were allowed to stay out after 8pm on the Labour Day, arguments could occur and the situation might get out of control.
Thungthon police station commander Pol Col Kraithong Chanthong said a group of Mon entertainers sought permission for holding concerts from April 28 to 30 but he had declined to approve it for fear that the concert goers would start fighting.
