The ICC announced the decision via Twitter on Sunday, and later said that Chandimal had pleaded not guilty.
Match referee Javagal Srinath of India “will hold a hearing following the conclusion” of the ongoing test, the ICC said.
Sri Lanka had resumed play on day three on Saturday under protest after delaying the start and strongly denied it tampered with the ball in St. Lucia.
The visiting team was charged with altering the condition of the ball by umpires Aleem Dar and Ian Gould, who reviewed video of West Indies’ first innings on Friday. They penalized Sri Lanka before play on Saturday with a change of ball and the award of five runs to West Indies.
Sri Lanka protested by refusing to leave its dressing room for nearly 90 minutes. Then the team went out to the middle and walked back to the boundary, where arguing with officials continued for another 40 minutes.
Sri Lanka Cricket advised the team to play “under protest,” that team management said no players “engaged in any wrongdoing,” and it would take all steps to defend any player charged with “any unwarranted allegation.”
The West Indies resumed day three on 118-2, which was bumped up to 123-2 by the penalty runs. But the home side was all out in quick succession after tea for 300, a lead of 47 on the first innings.
At lunch Sunday on Day 4, Sri Lanka was 136-4 in its second innings _ leading West Indies by 89 runs _ with Chandimal 27 not out off 82 balls.
West Indies leads the three-test series 1-0.
