The vehicle ran 550 meters at full speed, doing zigzag and stumbling over hundreds of people who were in the area, to finally hit a commercial post on the road.

The two passengers who were in the vehicle fled the place on foot in the narrow streets of Raval, a multicultural neighborhood where tourists, locals, pakistanti immigrants and prostitute have lived together in harmony for many years.
