Sanjeev Chawla, an alleged bookie and key accused in one of cricket's biggest match-fixing scandals that involved former South African captain Hansie Cronje, was extradited from the UK on Thursday, Delhi Police said, marking the first high-profile extradition of its kind between the two countries.

The 50-year-old British national, accompanied by a Delhi police crime branch team from London, reached Delhi this morning and will now undergo the procedural medical examination, a senior police officer said. After completing the formalities, the crime branch will question Chawla at its RK Puram office, the officer added.
