Pakistan cricketer Nasir Jamshed was one of two men arrested by British police on Monday in connection with the spot-fixing scandal that has engulfed the Pakistan Super League (PSL).
The arrests were announced by the National Crime Agency (NCA) on Tuesday as part of what it described as " an ongoing investigation into international cricket match spot-fixing".
The NCA did not name the men but Press Association Sport understands Jamshed was arrested and then released on bail, pending further inquiries, until April.
Jamshed, who has scored three centuries against India for Pakistan, was provisionally suspended from all forms of the game by the Pakistan Cricket Board (PCB) on Monday.
This move followed a PCB decision to suspend two other Pakistan batsmen, Sharjeel Khan and Khalid Latif, on Friday for alleged breaches of its anti-corruption code.
On Saturday, the governing body revealed it has also questioned three other players capped by Pakistan - Zulfiqar Babar, Shazaib Hassan and Mohammad Irfan - but they have not been suspended and remain with their PSL teams.
Jamshed, a 27-year-old opener who last played for Pakistan in 2015, was not selected in the PSL draft, while Sharjeel and Latif were playing for Islamabad United.
The PSL, a five-team Twenty20 event, started last week. It is largely based in the United Arab Emirates, with the final scheduled to take place in Pakistan next month.
PSL chairman Najam Sethi said last week: ''We will not tolerate any form of corrupt activity - and as this investigation proceeds, we will not hesitate to take further decisive action as appropriate.
''The investigation of the PCB anti-corruption unit, backed by the (International Cricket Council Anti-Corruption Unit), has been effective in dealing with this case to date - and we will continue to work in the closest collaboration as the investigation proceeds.
"We are all absolutely committed to relentlessly pursuing anyone who would seek to damage the integrity of our sport.''
