JOHANNESBURG, Jan 30: South African police have investigated an alleged death threat against West Indian umpire Steve Bucknor and found there was no substance to the threat.

United Cricket Board of South Africa media manager Gerald de Kock told Reuters on Sunday: "The matter was investigated at a very high level and no substance to the threats was found."

Bucknor, criticised by both the media and players for his performance in the fourth and fifth Tests between South Africa and England, said he and co-umpire Aleem Dar had received death threats on the final day of the fifth test at Centurion Park.

The threats were allegedly made in a phone call to the chief executive's office at the ground. -Reuters
