Revellers gathered around shops at the Dak Bungalow roundabout in the heart of the state capital for the customary 'thandai' and 'paan'.
A large number of people flocked to a water park on the outskirts of the city to enjoy Holi on the lines of the the 'La Tomatina' festival of Spain.
Ripe tomatoes were thrown at each other, with colours also being used as there were dances to catchy Holi songs.
Political bigwigs including Chief Minister Nitish Kumar and RJD president Lalu Prasad kept away from the celebrations.
Director General of Police Abhayanand played drums and cymbals and sang Holi songs at his residence with officials and policemen attending the celebrations.
"Policemen don't get leave on Holi. They can't go home to celebrate. We want to extend our best wishes to the people of the state and assure them that they can celebrate the festival without any worry," Abhayanand said.
