KARACHI, June 14: The car bomb used in the attack on the US Consulate General on Friday was controlled by a remote device, well-placed sources in the police said.

They said the powerful bomb was planted in a Toyota Corolla of 1981 model, belonging to the Khanum Motor Training School, which was used in the terrorist activity.

When the DIG for Investigation, Fayyaz Leghari, was contacted, he said: “We are trying to determine whether the bomb was planted in the Suzuki Hi-roof or in the Toyota Corolla carrying four women. Maybe the bomb was in the Corolla, but we have to investigate it further.”

The sources in the police said the bomb was planted in the car in the recent past as the criminals knew the routine of that car, which usually went to the driving licence branch. As the car was carrying four women, it was not checked by the police.

They said the women drivers, who were still learning driving at a training school, drove their cars slow and remained to the extreme left.

Those, who planted the bomb, either were following the car or waiting for it at the Frere Garden. As the car reached near the US Consulate, they pressed the button of a remote device exploding the bomb, which was so powerful that it blew the car into pieces.

The criminals did have access to the driving school and used the car for the terrorist activity. The women riders never knew about the presence of the bomb.
