London, Sep 9 (IANS) The International Cricket Council (ICC) has now asked Pakistan captain Salman Butt and wicketkeeper Kamran Akmal to hand over their phone records during the World Twenty20 in the Caribbeans.

The Daily Telegraph reported that the ICC's Anti-Corruption and Security Unit (ACSU) has asked Butt and Akmal to provide the mobile phone numbers they used and records of calls made during the tournament in May.

The demand was made in a letter sent to the pair at the end of last month’s Oval Test against England, a week before the spot-fixing exposé in the News of the World.

In the same letter, the ACSU also asked the duo to provide similar details for Asia Cup in Sri Lanka in June.

Butt has been suspended, along with Mohammad Asif and Mohammad Aamer for allegedly being involved in spot-fixing during the Lord’s Test.

The daily also reported that the ICC has informed Akmal that he is also under investigation but remains part of the Pakistan squad for the NatWest Series against England.

Butt, Akmal and Aamer were members of the Pakistan team that lost in the final over of a remarkable semi-final against Australia in St.Lucia when Mike Hussey hit three sixes in four balls to win the match.

How could Pakistan lose a winning match when comfortably placed, perplexed watchers of the game have since asked.

Butt and Akmal also opened the batting in a Super-Eight match against England that they lost in the tournament. During that match Pakistan spilled three catches, of which two very simple ones by off-spinner Saeed Ajmal, and they missed a run-out against Kevin Pietersen as he guided England to victory.

Pietersen was comfortably beaten by a throw from point when on 64 but, despite collecting the ball cleanly, Akmal missed the stumps.
