The Bruhat Bengaluru Mahanagara Palike (BBMP) has launched a toll-free number for the citizens to complain about problems created by monkeys, birds and snakes in the city. Residents can register their complaints either on the Namma Bengaluru Sahaaya 2.0 mobile app or can dial 1533. Repeated attacks by groups of monkeys in several residential societies were reported in Bengaluru recently.
