Rioting crowds forced cricketers to retreat to their dressing rooms as projectiles reached the outer field of the Premadasa Stadium in Colombo during the third one-day international between Pakistan and hosts Sri Lanka yesterday. Police deployed anti-riot squads to clear two blocks of stands near the scoreboard as rival groups of spectators clashed, pelting stones into the grounds from outside the stadium after they were forced out during Sri Lanka`s run chase in the day-night match.The hosts, chasing Pakistan's 316-4, were struggling at 158 for 7 in the 34th over when the disturbances at the grounds in the Sri Lanka capital forced the umpires to order the players to their dressing rooms until the situation was brought under control.Several vehicles at the stadium were damaged due to stone throwing. However, no players were hurt, and the match resumed after a nearly 20 minute delay. Later Pakistan won the match by 135 runs, and now lead the five-match ODI series 2-1.
