It has emegered that "several" of Pakistan's players have been monitored by the ICC's Anti-Corruption and Security Unit (ACSU) for some time
The Pakistan spot-fixing case
In September 2010 the ICC suspended three Pakistan players - Mohammad Amir, Mohammad Asif and Salman Butt - on allegations of what was later defined as spot-fixing. They were alleged to have carried out specific on-field actions, including bowling no-balls at pre-determined times, during the Lord's Test against England on the instance of a bookie. The three were later handed long bans by the ICC before the matter moved to the British Crown courts, where all three were convicted and sentenced to spells of detention.
