Cricket is the live-blood of Pakistan and ball tampering has not been new. People have been involved in doing so since long. Though it was first reported in 1977, from then till today care must be taken on the end of ballers to avoid punishments.

He was accused of putting Vaseline on ball, as he had put the petroleum jelly on his brows to avoid sweat running into eyes. It accidentally transfered to ball when he swept the sweat on the ball in hot weather.
