In one case, drug suspect Jakha Jakor was shot dead in Chiang Mai on Nov 13, when 6mn speed pills were seized, along with a gun, a grenade, three mobile phones and a pickup truck, Pol Lt Gen Sarayut Sa-nguanphokhai, chief of the Narcotics Suppression Bureau, said at joint media briefing by the NSB and the army, reports the Bangkok Post.
He said Jakha was killed after police learned that a drug network led by a Muser tribesman in Tambon Ban Luang of Mae Ai District planned to smuggle drugs into Thailand through Mae Ai and Fang district of Chiang Mai on Nov 13.
Soldiers and narcotics suppression police manning a checkpoint in Mae Ai district signalled a pickup truck to stop for a search. Instead, the driver opened fire at them and attempted to accelerate away, Lt Gen Sarayut said.
In the ensuing exchange of gunfire the driver was shot dead, Pol Lt Gen Sarayut said.
He said Jakha had a criminal record and was also wanted on an arrest warrant issued by the Lampang provincial court for smuggling 400,000 meth pills in 2017.
Seven members of his network, his wife, son and friends, had been caught earlier.
Warrants had also been approved for the arrest of five other members of his gang who were still at large, the NSB chief said.
