The streets of Bangkok are very congested with traffic which probably explains why there are no police car chases in the city. At the same time, there are also some very narrow lanes that are not suitable for cars or even motorcycles. This is where the Police Bike Patrol become useful. These guys are from Chana Police Station near Khao San Road. There are about twenty of them and they are made up of volunteers and fulltime policemen. They patrol the tourist areas on their bicycles.
