Police and soldiers intercepted more than 850 young motorcyclists early Sunday and arrested 411 as the young people flocked to Vibhavadi Rangsit Road and a Saraburi petrol station for gatherings that alarmed motorists.
A member of the motorcyclist group in the Vibhavadi Rangsit area said they met early Sunday for a "charity trip", but the large size of the group worried motorists and police who were looking out for street racing, banned by the National Council for Peace and Order (NCPO).
About 30 police surrounded the riders who had filled up the express lanes near the Bang Khen intersection. They detained 227 men and 31 women. There were 59 teenagers, including some aged under 18 years old, including pillion riders.
