"It is a hypothetical situation. Any comment would be speculative," Delhi police commissioner K K Paul said when asked whether the players would be questioned for their alleged involvement in the case as had been apprehended by UCBSA.
The UCBSA has reportedly sought an assurance from the Board of Control for Cricket in India that no police action will be taken against Gibbs and Boje when they arrive for a One-day International series in October this year.
"We have not received any letter in this regard," said Paul who incidentally headed the crime branch when it unearthed the match-fixing racket in 2000.
Cracking of the case and investigations of Delhi police had led to a startling confession by former South African captain Hansie Cronje.
Paul pointed out that Delhi police had issued rogatory letters four years back seeking help from that country in the investigations.
"We have written to South African authorities long time back and our desires are well projected," he said.
Delhi police has requested the South African authorities to help in enabling questioning of the cricket players to get a clearer picture of the racket and unravel all the names involved in it.
