Riaz took 5-63 on his Test debut at The Oval in August
Pakistan fast bowler Wahab Riaz will be questioned by police on Tuesday in relation to allegations of corruption.
The 25-year-old made his debut in The Oval Test against England and also played in the match at Lord's.
Pakistan trio Salman Butt, Mohammad Asif and Mohammad Amir have already given police statements.
They have been accused of spot fixing during the Test series but have not been charged by the police and are expected to return to Pakistan.
"Since the players have not been charged we have informed Scotland Yard that they will be travelling back to Pakistan within the next few days," said Pakistan Cricket Board chairman Ijaz Butt.
However, the trio have been charged and provisionally suspended by the International Cricket Council's Anti-Corruption and Security Unit.
