Immigration police received a tip-off that three tourists, living together in Chalong, seemed to be overstaying. The tip off did not, however, say where they were living.
A second tip-off came on Saturday, saying that the trio had been seen in the vicinity of the PTT Petrol Station on Chaofa West Rd.
Pol Capt Angkarn Yasanop and the team hurried over to the patrol station and spotted the three, asked for their passports, and confirmed they had overstayed their permits.
The three are Damien Yann Minnig, 31, from Switzerland, whose permit expired in January 1, 2011; Frank Georges Vincent Fechant, 50, from France, whose permit expired on February 17 this year; and Soulimant Loic Yves Barthelemy, 23, also French, whose permit was valid only until February 22, 2013.
All three admitted to overstaying and were sent to Chalong Police Station to be charged.
They are expected to be fined and then deported.
