Light ans Easy - Something Burning?

I was about to sleep when I went out to the balcony of my house and saw this thick billowing smoke in the distance. I think it nos just a normal smoke but must have come from some building burning. This picture was taken at 12.15 a.m using my Olympus AZ 1 camera and night scene function.

The incident might be somewehere near Sri Petaling or maybe Desa Tasik.
