Pakistan on Tuesday said it would investigate allegations of match fixing in a domestic Twenty20 match last week.

Former batsman Basit Ali made the charges over the T20 Cup match between the Sialkot Stallions and Karachi Dolphins on February 11.

The Pakistan Cricket Board (PCB) said it had appointed a three-man committee to probe his claims. Basit openly criticised the match in television commentary after Sialkot, who had already qualified for the knock-out stages, were bowled out for a paltry 91 in the last group match.

They then did not try to win the match against a weak Karachi side who were by then out of the knock-out stages.

"I saw that batsmen were getting out deliberately and then Sialkot did not try to defend the total by bowling non-regular bowlers," Basit told AFP.

Led by former Pakistan captain Shoaib Malik, Sialkot lost the match by six wickets.

Sialkot protested over the allegations by playing their next match on February 12 with black armbands and successfully demanded Basit's removal from the commentary panel.

The PCB said the fact-finding committee would submit its report to PCB chief operating officer Subhan Ahmed within a week.

Malik was banned for one Test and fined 75 percent of his match fee after admitting to deliberately throwing a match in the first edition of the national Twenty20 in 2005.

Former captain Rashid Latif backed the latest allegations levelled by Basit.

"What Basit is saying has weight and must be investigated," Latif said earlier this week.

Match fixing has long haunted Pakistan cricket.

Former captain Salim Malik and paceman Ata-ur Rehman were banned for life after a match fixing inquiry in 2000.

Australian players Shane Warne, Mark Waugh and Tim May alleged Malik, then Pakistan captain, offered them bribes to underperform during their tour of Pakistan in 1995.

Former captains Wasim Akram, Waqar Younis, Saeed Anwar and Inzamam-ul Haq were among six players fined by the same inquiry in 2000.

Three Pakistani players -- Salman Butt, Mohammad Asif and Mohammad Amir -- were banned for a minimum of five years on charges of spot-fixing during Pakistan's tour of England in 2010.

Pakistan leg-spinner Danish Kaneria is also serving a life ban for spot-fixing during a county match in England in 2009.
