A gunman was arrested after firing shots at ‌a local government office on the outskirts of Thailand's capital on Monday, officials said, just days after a teenager's killing spree at a school in the same province reignited debate over gun control.

The suspected shooter, a former lawmaker, fired at a senior provincial official and his driver, said Major General ​Dejrapee Kongdee, the police commander of Nonthaburi, which borders Bangkok.

"There were two people wounded, who have been sent ​to hospital for treatment," Dejrapee told Reuters.

Thailand has been reeling from a 14-year-old boy's rampage on Friday -- ⁠first at his home and then at the Debsirin Nonthaburi School -- that left nine people dead, including the shooter, and over ​20 wounded in the country's deadliest mass shooting in nearly four years.

Thai school children returned to their classrooms on Monday, some going through ​metal detectors and other checks, as Prime Minister Anutin Charnvirakul reiterated his intention to tighten gun controls in the wake of Friday's school shooting.

At Debsirin School in Bangkok, a sister institution to where Friday's shooting took place, authorities installed metal detectors and stepped up security as students returned to classrooms ​after the weekend.

School director Withan Promsintusak said officials had acted immediately after the attack, introducing weapons screening to reassure parents ​and protect students.

"We never imagined that a school, which should be the safest place, is where something like this would happen," he said.

ThidaratSongrat, ‌the ⁠54-year-old grandmother of a student, said weapons screening was necessary because schools could not otherwise determine whether students might be carrying dangerous objects.
