As many as 4,000 auto drivers have been issued challans since October 28 when a special drive against errant auto drivers was launched.
According to Satyendra Garg, Joint CP Traffic, the violations included permit violations, overcharging, refusal to ferry passengers, jumping red lights and other misbehaviour.
"In three days, about 4,000 prosecutions but they apparently do not bother. What a city we are in," Garg wrote on Facebook wall of the Delhi Traffic Police (DPT).
He informed that intensive drive against improper parking in the city's markets was also launched Saturday.
"Now festival pressure is on and... there is flagrant improper parking in market places which are over-crowded. We are shifting focus because of security reasons," he added.
