A gunman killed a Thai official inside a ‌local government office on the capital Bangkok's outskirts on Monday.

Axar.az reports, citing Reuters, that the shooting came days after a teenager's shooting spree at a school in the same province reignited debate over gun control.

Police said the suspected shooter, former lawmaker Chalong Riewrang, fired at the chairman of the Provincial Administrative Organization in Nonthaburi, which borders Bangkok, because of a disagreement over borrowed money.

"The motive ​was personal," Police Lieutenant General Wattana Yijin told reporters, adding that the provincial official's driver was also wounded but is not in ​a critical state.

The official later died of his wounds at Nonthaburi's Phra Nang Klao Hospital, its director Dr. Sakol ⁠Sookprome told Reuters.

In a statement to reporters while in police custody, Chalong said that he had gone to confront the victim over a long-standing dispute but the ​latter declined to talk things out.

"But when he was driving away, he pulled a gun," Chalong said, referring to the victim: "I fired."
