This CCTV in India captured the moment of a freak accident! 

Road rollers are heavy vehicles you've seen trundling along at a snails pace and flattening out the freshly laid road and tar. 

It is not clear from the video what caused this road roller to go out of control!! It moves at a surprisingly fast speed with the driver unable to control anything. It then crashes into a house completely destroying the wall and probably even the house. 

Unexpected scenes are not uncommon in india, but I have never seen a roadroller crash like this before!! Itnis likely that the brakes of the roadroller were not working and had not been checked or maintained well. There is a possibility that the road was a downward slope and this caused the roadroller to gain speed and momentum that resulted in the crash.
