Islamabad, Pakistan (CNN) -- A fourth Pakistani cricket player was questioned on Tuesday, Scotland Yard said.
This comes amid probes over "spot fixing," which involves deliberately throwing parts of a game, rather than the whole match.
Scotland Yard didn't say who was interviewed.
But Tafazzul Rizvi, the Pakistan Cricket Board's legal adviser, says Wahab Riaz was to be questioned in connection with the video that was released by the News of The World in which Riaz appeared, and British media reports said he was in fact interviewed.
Rizvi says the board is providing full legal assistance to the players and cooperating with police.
"No evidence has been shared with us by Metropolitan Police London," Rizvi said.
The betting scandal has rocked the cricket world, with allegations that members of the Pakistan national team were involved in spot fixing during Pakistan's Test series with England late last month.
Rizvi says the other three cricketers suspected of spot fixing returned to Pakistan after assuring authorities there that they would come back to London if asked to do so by the investigating agency.
The News of the World, the British tabloid that first reported the allegations, said players deliberately bowled "no balls," or fouls, at specific points in the game and that the alleged ringleader made 150,000 pounds (about $230,000) in the scam.
No players have been arrested over the allegations, but the three questioned by police -- teenage cricket star Mohammad Amir, Mohammad Asif, and team captain Salman Butt -- were provisionally suspended by the sport's governing body and charged with various offenses under the International Cricket Council's anti-corruption code.
Their team is continuing a two-month tour of England without them.
