"I don't mean to dare anyone. But if you are a troublemaker, you will surely be arrested and face legal action," secretary-general Weerasak Wongsombat said.

A new IT security system will record juvenile offenders on surveillance cameras and send a visual alert to a centre at the Vocational Education Commission office and police will go after them, he said.

"The cameras work around the clock," he said.

The signal will also be relayed to educational institutions, police stations and other police units. Weerasak said his office had joined hands with authorities such as the National Police Office and its Juvenile Aid Subdivision in the planned launch of the IT security project.

"We have already identified 17 places where student fights tend to break out," he said. The monitoring system would go online in the second semester with six cameras.

"But soon, cameras will be installed at all risky spots and we will also have 10 more mobile cameras," he said.

The system would also play a role in traffic work and public safety.

Weerasak said if his office had a bigger budget, it would encourage colleges under its

wing to adopt the security technology. Lt-Colonel Weerawit Wajjanapukka, deputy superintendent of the Juvenile Aid Subdivision, said the technology could help because if gang leaders were caught, the clashes would die down.
