Pattaya police chief Pol Colonel Apichai Krobphet said Niyom Sukcharoen, 64, faced a theft charge for refusing to report finding the Xiaomi Mi8 smartphone.
Apichai said police tracked down and arrested Niyom after Mikhail Sizov, 29, filed a complaint with police late on Sunday night that he dropped his phone in front of a restaurant at the entrance to Soi Sinsoi 7 in South Pattaya and someone took it.
Witnesses told police that they saw a taxi motorcyclist pick up the phone and drive off.
Niyom said someone made a call to the phone after he picked it up but chose not to answer it and took it home before being arrested.
