Thai authorities had caught more than 5,600 motorcycle racers and impounded over 17,700 bikes, 11 days after the night curfew was lifted.
The police intensified its operations to clamp down on the underground racing scene, particularly towards a racing group known locally as Vanz boys.
Thailand Prime Minister, Prayut Chan-o-cha, had previously warned against gatherings and street racings, ordering the police to crackdown on the illegal racing operations.
The Assistant National Police Chief, Pol Lt Gen Damrongsak Kittiprapas, stated on Thursday that the police stationed in Bangkok and the Provincial Police Region 1 had apprehended a total of 109 racers.
They had also confiscated 11,743 motorcycles and cited 3,088 shops for conducting illegal bike modifying operations.

The most common modification made on the impounded motorcycles were done on its exhaust pipes, giving off a loud noise. The word Vanz was derived from the sound produced by modified bikes.
The Thai police had also 668 parents of the apprehended racers on probation.
The number of recent complaints filed about illegal street racing has dropped from over 600 to less than 300.
