On May 9, at a match between the Kings XI Punjab and Rajasthan Royals played at Mohali near Chandigarh, pacer S Sreesanth ran up to bowl an over with a towel tucked into the band of his trouser.
The Delhi Police allege that this was a signal to bookies that he would now fix an over. He had bowled the previous over without the towel. (Read: Delhi Police explains spot-fixing arrests)
The deal, the Delhi Police allege, was that Sreesanth would tuck the towel to indicate spot-fixing and then would give the bookies some time to place as many bets as possible. On field, Sreesanth had warmed up a bit before beginning to bowl the over. He gave away more than 14 runs as fixed.
