(CNN) -- The Pakistan cricket board has suspended the central contract of wicketkeeper Zulqarnain Haider who walked out on the team during their one-day international series against South Africa in Dubai.
The 24-year-old flew to London after scoring crucial runs to help Pakistan win the fourth match to tie the series at 2-2 on Friday.
He later told a Pakistani television channel that he had received death threats from matchfixers after the one-wicket victory.
A statement on the board (PCB) website said Haider had breached his contract by leaving the team without informing the management.
Pakistan went on to lose the deciding match of the series on Monday by 57 runs.
The board said that a three-man "fact-finding" committee would attempt to establish the facts surrounding his disappearance.
The committee will include former Test player Intikhab Alam, the team manager.
The PCB said it was trying to get in touch with Haider, but had so far been unsuccessful.
Reports have said that Haider would be seeking political asylum in Britain and has announced his retirement from international cricket.
THe UK's Press Association said Haider had been in talks with the anti-corruption unit of the International Cricket Council (ICC).
Pakistan cricket has been dogged by corruption and three members of their team are currently suspended by the ICC while allegations of "spotfixing" during their Test series against England earlier this year are investigated.
