Two pedestrians sustained minor injuries when an unattended BEST bus, with its engine running, began to move forward, suddenly gained momentum, and crashed into a tea stall near Kannamwar Nagar bus depot in Vikhroli East in Mumbai on Saturday.

Sources said that the BEST (Brihanmumbai Electric Supply and Transport) bus driver had gone to the washroom without applying the parking brake. The police said the BEST bus started to roll down as it was parked on an inclined road.
