A fourth Pakistani cricketer has been interviewed by detectives under caution after claims of match-fixing, Scotland Yard said.
Fast bowler Wahab Riaz was questioned by officers after fellow players Salman Butt, Mohammad Asif and Mohammad Aamer were grilled for nine hours over allegations published in the News of the World last month.
The Pakistan Cricket Board (PCB) revealed last week that the bowler would be questioned.
A Scotland Yard statement read: "We can confirm that today, Tuesday 14 September, one further Pakistani cricketer was interviewed by appointment under caution."
The corruption controversy has engulfed the Pakistan cricket team during its tour of England.
Businessman Mazhar Majeed is accused of accepting £150,000 to arrange for Test captain Butt, Asif and Aamer to deliberately bowl no-balls during the fourth Test at Lord's.
Butt, Asif and Aamer have been suspended by the International Cricket Council (ICC). All three deny any wrongdoing.
Majeed has also been arrested and released on bail without charge.
