The Brihanmumbai Electric Supply and Transport (BEST) undertaking's bus, after ploughing through pedestrians and vehicles, entered into a residential society, Buddha Colony, and came to a halt, they said.

Three persons were brought dead from the crash site to nearby Bhabha Hospital, where 22 injured, including a teen girl, were undergoing treatment, said the officials.

Some of the injured were said to be in a critical condition. Multiple vehicles were damaged in the accident.

The bus bearing registration number MH01-EM-8228 was going from Kurla railway station to Andheri when the accident occurred, he added.

"It dashed into various vehicles over a 100-metre stretch and the RCC column of Solomon building. The windows of the bus broke on impact. Locals roughed up the driver," an official said.

Zeeshan Ansari, an eyewitness, said "I was standing in front of Royal Sweets shop along with my friends when I saw a bus being driven rashly. The bus suddenly dashed into multiple vehicles as well as pedestrians and entered Buddha Colony. We rushed and brought out the bus driver." "Many people were lying in a pool of blood. A crowd assembled at the spot and started moving the injured to hospital," Ansari said.

Zaid Ahmed, a 26-year-old resident of the area, said he was leaving his house to go to the railway station when he heard a loud noise.

"I ran to the spot and saw a BEST bus had hit pedestrians, other vehicles, including an autorickshaw and a three cars. I saw some dead bodies in front of my eyes. We rescued the passengers in the autorickshaw and took them to Bhabha Hospital in another three-wheeler. My friends also helped in providing relief to the injured," Ahmed recounted.
