Asif was detained in Dubai on June 1 for alleged drug possession, while returning home after playing in the Indian Premier League.

PCB chairman Nasim Ashraf on Monday said the Board would carry out an inquiry against Asif once he returns home.

"It is too early to say anything but yes our anti-doping regulations are now complaint with the World Anti-Doping Agency and in this particular case also we have to follow their regulations," Ashraf said.

"We are hopeful he will be released and allowed to return home but since it is an incident involving drugs no matter how small the quantity, he could be suspended from playing cricket until the inquiry is conducted against him," he added.

The PCB Chairman said the board has used all legal and diplomatic channels to get Asif back home.

"I don't know if they decide to deport him or just send him back home. But at the moment our first priority is he is cleared of this case which is bad for Pakistan cricket," Ashraf was quoted as saying in the local media.
