Pakistan's tainted trio of Salman Butt, Mohammad Asif and Mohammad Aamer returned home with tight security after being given permission to leave by the London police.
The trio were reportedly greeted with angry protests and slogans outside the airport.
Their tour of England had come to an end before the start of the one-day series after they were questioned and released by police following their alleged involvement in 'spot-fixing'.
The trio have denied any wrongdoing and have claimed to be innocent.
A spokesman for the Metropolitan Police in London confirmed it was aware that the trio were leaving Britain and said the players had promised "through their solicitor to return to assist the Metropolitan Police Service inquiry in due course."
Media reports also suggested that the players have agreed to 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.
