NDTV quoted Col Anil Kaul, who was in charge of the Pakistani team during their stay for the Champions Trophy, as saying that Woolmer was irritated with Shoaib's behaviour and soon an argument started between the duo over playing music in the team bus.
''...boys were listening to Hindi songs when Bob Woolmer removed the iPod and put on an English song. Shoaib got up and again changed the music, put on a Hindi song,'' said Colonel Kaul.
''Woolmer kept quiet and then started making fun of the song.
This was too much for Shoaib. He suddenly got up and gave Woolmer a tight slap. Everyone was stunned and quickly intervened,'' he added.
And hours after the incident, Pakistan team management announced that Shoaib and Mohammed Asif were being sent back home after failing a dope test.
According to the channel, the same night Shoaib was involved in another brawl during the champions Trophy after the team dinner.
The pacer reportedly started a brawl at a disco after forcibly trying to dance with a girl.
And it was not the end of the story, said Col Kaul.
''...Shoaib went to the floor where the Indian team was staying and started banging on the doors. He accidentally banged on the door of Indian coach Greg Chappell and his wife came out, dressed in her night clothes.
''Shoaib made some comments about her. The next morning, I was having breakfast with the Pakistani team manager when Woolmer stormed in. He said even Chappell has complained about Shoaib and strict action must be taken,'' he revealed.
