Scotland Yard, asked to assist in the probe of the death of Pakistani opposition leader Benazir Bhutto, has delivered its findings to President Pervez Musharraf, but it is unknown whether or not the report will ever go public, the Chicago Tribune reported Wednesday.

Investigators were hard at work over the last week, interviewing hospitalized survivors of the Dec. 27 attack and scrutinizing morgue records, the Tribune reported.

The cause of Bhutto’s death is still up for debate. A video shows a gunman pointing his weapon at the opposition leader moments before a homicide blast. Originally, the Pakistani government said Bhutto had died from blunt force trauma after hitting her head against the sunroof of the car in which she was riding.

Musharraf was the target of furor last week after he said that Bhutto’s death was partly her own fault after she ignored militant threats against her.

Bhutto’s son, Bilawal Bhutto Zardari, said he would only be satisfied with a U.N. investigation into her death.
