LAHORE, May 14: The Pakistan Cricket Board (PCB) has refused to make any comments on a press report published on Monday which has quoted the Scotland Yard sources as saying that Pakistan coach Bob Woolmer's death was caused due to a heart attack.

A PCB spokesman on Monday clarified that since the board had not received any official communication from the Jamaican police investigating the death of Bob Woolmer, it was unable to offer any comment on the situation.

"Let the official version come from the Jamaican police on Woolmer's death and only then will we be able to comment on it," the spokesman said.

Woolmer died under mysterious circumstances on March 18 in his hotel room at Kingston during the World Cup and the Jamaican police have been treating the coach's death as a murder case although no definite breakthrough has been made in the investigations so far.
