Narcotics Suppression Bureau police have arrested three African men on charges of possession of crystal methamphetamine with intent to sell.
Alfred Leboea, a 30-year-old Lesotho national, and Nigerians Peter Ebuka Iloh, 36, and Eze Clement Agu, 30, were detained on Wednesday with 2kg of crystal methamphetamine in 10 small bags on Lang Suan road, NSB chief Rewat Klinkeson said on Thursday.
Mr Iloh and Mr Leboea were arrested at the Urbana Langsuan Hotel and Mr Agu at a 7-Eleven store in the same area.
Pol Maj Gen Rewat said the bureau worked on a tip-off from informants that the three were sending the drug to African customers in Bangkok and put them under surveillance before the arrest.
They were charged with drug possession and intent to sell.
Their arrest underlined concern of anti-drug police about widespread drug activities involving Africans staying in the country, he said. African nationals are being targeted by the bureau after reports that 15,000 visitors from the continent are living illegally living in Thailand.
