The Indian security officer of the Pakistan team in the tournament, Anil Kaul, made allegations to Indian television channels that fast bowler Shoaib Akhtar slapped coach Bob Woolmer on the team bus in Jaipur.
He also alleged other rude behaviour by Shoaib and other players.
''We have sent our protest in writing to the ICC as the Indian board has distanced itself from Kaul's appointment,'' Saleem Altaf, the PCB's director of cricket operations, told Reuters today.
''We have asked them to investigate the matter and take some action against this fellow based on their findings,'' Altaf said.
