More than 100 people were arrested from across the city on Holi on charges of disorderly conduct, police said.

The offences include racing, rash and negligent driving, drink driving and riding motorcycles without helmets.

Lalbazar had asked all police stations in the run-up to Holi to remain vigilant on Thursday.

“We booked a lot of helmet-less bikers. Usually, people have a tendency to flout rules on festive days but we wanted to stop that. Festivals must be celebrated following rules,” a police officer said.
