Mohammad Aamer, one of three Pakistan cricketers embroiled in betting scam claims, reported to a British police station on Friday.
Fast bowler Aamer arrived at Kilburn Police Station, near Lord's cricket ground in north London, where he is expected to be interviwed by detectives.
Police are also expected to question Pakistan's Test captain Salman Butt and Aamer's fellow bowler Mohammad Asif on Friday.
London's Metropolitan Police offered no comment when contacted by AFP.
Aamer's arrival came as cricket's world governing body, the International Cricket Council, was to explain the provisional suspensions and corruption charges hanging over the trio in a press conference at Lord's.
So far, police have bailed without charge a 35-year-old man arrested on suspicion of conspiracy to defraud bookmakers as part of their probe into the alleged "spot-fixing" scam surrounding the Pakistan team.
