A total of 72 people, including three Thais, were arrested during coordinated police raids at 75 locations nationwide frequented by foreigners early yesterday morning.

Forty-six others (23 from Myanmar, nine from India, seven from Cambodia, five from Laos, and two from Vietnam) were charged with illegal entry.
The remaining 15 (10 from Myanmar, three Thais and one Nigerian) were charged with various other offences, Pol Maj Gen Surachate said.
The string of raids was the 20th in the ongoing crackdown dubbed "X-Ray Outlaw Foreigner''.
