Bangladesh Football Federation (BFF) yesterday asked Bangladesh Premier League outfits Brothers Union and Arambagh KS for a second time to explain their positions over suspicions of match-fixing and betting during a few league matches.

The game's local governing body asked for a reply within 48 hours after AFC queried about five suspicious matches of the ongoing league.

"For two to three weeks, we have been working on five suspicious betting matches involving Arambagh KS and Brothers Union," said BFF general secretary Abu Nayeem Shohag.

"We have sent letters to the clubs today for a second time to explain their positions over specific allegations of match-fixing and online betting. We will send a third letter tomorrow," Shohag continued, adding that they are likely to send details of their investigation to AFC by mid-March.

Brothers have already replied to the first letter denying the allegations while Arambagh KS were supposed to reply last night.

AFC, which monitors the top-tier league matches in different countries through a third party, raised doubts over five matches – Arambagh vs Abahani, Arambagh vs Sheikh Russel, Arambagh vs Mohammedan, Brothers vs Bashundhara Kings and Brothers vs Abahani.

Replying to a query, BFF competitions manager Zaber Bin Taher Ansari said, "The opponents of Arambagh and Brothers Union are not involved with these allegations which is why we did not ask them for any explanation."
