The Pakistan Cricket Board has assembled a three-man committee to conduct an inquiry into the Mohammad Asif affair.

The fast bowler arrived back in Lahore early on Friday morning protesting his innocence despite his lengthy detention in Dubai.

The 25-year-old had been held in the emirate since June 1 after a small quantity of powder was found in his possession by authorities at Dubai International Airport.

He was finally released on Thursday after local prosecutors opted to deport the pace bowler rather than charge him even though they alleged he was guilty of carrying opium.

"We want the facts to be revealed in this case," PCB chairman Nasim Ashraf told reporters.

"I have scheduled a meeting with Asif later today (Friday). Further action will be taken once the three-member committee submits its report."

Ashraf revealed the names of those on the committee would be announced later on Friday.

The PCB also released a statement which read: "We appreciate the professional manner in which this whole issue was dealt with by the Dubai police, prosecution department and the UAE authorities.

"The PCB intends to conduct an immediate inquiry into this matter, as per its policies and procedures, once the official records are received from the UAE authorities."
