Police officials probing the elimination of Pakistan's Minority Affairs Minister Shahbaz Bhatti have neither been able to access his cell phone nor his driver, which could help yield valuable clues.Bhatti's cell phone is still in the custody of his family, and the driver- Gul Sher- had gone with the casket to the slain minister's native village to attend the burial. "The minister's family had not raised any suspicions over the character of their most trusted driver," The Express Tribune quoted a police official, as saying.However, he confirmed that there were contradictions in the statements made by the driver. "There was also difference in the statements of witnesses and the driver over the account of the incident," he said."Some witnesses said three gunmen had disembarked from their vehicle to shoot at the minister while Sher maintained it was only one," the official added. Also, the driver had stated that he had saved his life by ducking down when the shooter fired at the windscreen of the car. This claim was also challenged by certain witnesses, who stated that Gul Sher had disembarked from Bhatti's vehicle on seeing the gunman, before the latter had opened fire.
