Colombo: A practice net bowler is being suspected in the ongoing probe on a bookie approach made on Sri Lanka's Kusal Janith Perera and Rangana Herath, Sports Minister Dayasiri Jayasekera said on Saturday.

"We will make a complain at the FCID (Financial Crime Investigation Division) against him," Jayasekera told reporters, adding that the bookies are believed to have approached the two players through the 'net bowler'.

Sri Lanka have started a probe following a complaint lodged by both Perera and Herath that they were approached by bookies to underperform during the Sri Lanka-West Indies Test match played in Galle mid October. Sri Lanka crushed the Caribbeans in that match. Perera was subsequently found to have used a banned steroid following a random test.
