Suspended Pakistan cricketers Salman Butt, Mohammad Asif and Mohammad Amir will return home on Friday.

The trio are at the centre of allegations surrounding spot-fixing on Pakistan's current tour of England.

Pakistan management confirmed the players would be flying home on Friday but added that that did not mean they were cleared from the ongoing criminal investigation.

"They have not been charged by the police with any offence," Pakistan Cricket Board chairman Ijaz Butt said in a statement.

"They have fully co-operated with the police in their inquiries and maintain that they are innocent of any alleged wrongdoing."

"They have agreed with the police to return to England if the police request them to do so to further assist the police in their enquiries."

"I have no further comments to make at this time."

Butt, Asif and Amir were provisionally suspended by the ICC last week after allegedly accepting money for bowling no-balls in the fourth Test at Lord's against England.

Their solicitors Addleshaw Goddard released a statement on Friday morning.

"The Metropolitan Police has been notified that Mohammad Amir, Mohammad Asif and Salman Butt will return to Pakistan later this morning," the statement read.

"The players are looking forward to being reunited with their families. They remain available to co-operate fully with the police investigation and have each given undertakings to return to the UK if required to do so."

Rain has delayed the start of the first one-day international between Pakistan and England at Chester-le-Street on Friday.
