The tainted cricketer, was jailed for 30 months last year in the month of November on charges of accepting corrupt payments during the Lord's Test against England in August 2010.
"He is due to arrive back in Pakistan later this evening and will begin rebuilding his life and hopes to return to cricket. Salman Butt has had to endure a great deal of suffering, strain, pressure and humiliation over many months both personally and on behalf of his family," said Yasin Patel
"His return back home will allow Salman to spend time with his family and relatives. He will get to see and hold his son whom he has not seen since his birth in November last year. He can now return to his beloved homeland, start to rebuild his reputation and begin the long process in his efforts to return back to top-level cricket," says Yasin Patel, Butt's lawyer after the cricketer was released from the prison on Thursday.
Alongwith Butt, two other Pakistan cricketers - Mohammad Aamer, Mohammad Asif and agent Mazhar Majeed were accused of bowling two illegitimate deliveries in return for money and were found guilty of spot-fixing.
Reprimanded for the same reason, Aamer served a jail sentence for six months and was released in the month of February while Asif was released in the month of May after serving a 12 month sentence by the court.
Butt's father on Wednesday claimed that his son would be released soon after serving a 10-month jail sentence.
"We expect him to be released tonight," he told a private channel in Pakistan.
"My son's good behaviour has led to the decision and he will be in Pakistan in the next three to four days," Zulfiqar, Butt's father added.
ICC had banned the tainted trio for atleast five years and also suggested to involve rehabilitation for former stars.
Interestingly, Aamer has started with the rehabilitation last week. Pakistan's tainted trio has the right to appeal against the ban in the Court of Arbitration for Sports in Switzerland.
The talented youngster, Aamer who pleaded guilty during the trial, decided not to appeal while Asif and Butt are keen on challenging the punishment.
