The scene: A Mercedes-Benz rams into a TransCab taxi. The cars look like two rams butting heads, with the Mercedes' wheels spinning furiously.

Suddenly, the doors of the taxi open and a woman and child flee from the passenger seat, running onto the pavement.

Then the Mercedes hits and shears off the site of the cab and moves forward, slamming into an SBS bus. It then moves on.

This scene is from a video capturing a part of Monday night's seven-vehicle mayhem, caused by the Mercedes, along Victoria Street. It has gone viral on YouTube and Facebook.

The chain collision, which happened at about 8.30pm on Monday, occurred at one junction before the Ferrari crash that killed three people last year.

Responding to The New Paper's queries about Monday's accident, an SBS spokesman said: "Our bus sustained damage to the left side panel as a result of the collision. Fortunately, none of the passengers on board were hurt and they were transferred to the next bus."

The incident began when the Mercedes was on the junction of Victoria Street and Middle Road, said Mr Daryl Wee, 51, whose cab was also involved in the collision.

Because of the impact, the Comfort cab knocked into the back of a blue lorry in front of it.
