The incident happened in the tournament opener where Challengers defeated Thunder.
The incident, for Santokie's mistakes felt deliberate, made everyone sit up from their chair with Sylhet Thunder team director Tanjil Chowdhury confirming he has asked the Bangladesh Cricket Board to investigate the matter.

"The no-ball that he bowled is suspicious," Chowdhury, one of seven team directors in the league by BCB, said. "He (Santokie) is not yet called by the BCB but I have lodged my complaint. I verbally requested CEO and Morshed [BCB anti-corruption head] to investigate the matter[ no ball]."
"We don't have anything to do with the playing XI. It is up to the management and the coach. I asked the sponsors whether they interfered in the playing XI and they are refusing to say anything."
"Now we have to talk with the team management and know whether anyone influenced them to play Santokie because it seems he is associated with spot-fixing."
Santokie conceded 34 runs off his four overs, picking up a wicket in his team's five-wicket defeat to kickstart the season.
Tanjil was also suspicious of the team sponsors and informed that they insisted on picking certain players during the draft which left him confused.
"On the day of the players draft, there was a lot of conflict between us," he said. "Me and team director Sarowar Imran was convinced with certain decisions. The sponsors were insisting on taking a few cricketers and we were not sure why they are insisting to pick those cricketers."
"We had the chance to pick Nayeem Sheikh and other players. But they preferred to pick players like Sohag Gazi and Santokie. That is the reason we have started doubting them. I have informed BCB governing council members and the BCB president."
