A camera installed on a Motorway Toll Plaza failed to clearly show the face of the driver of Kashmala Tariq's vehicle that killed four youth in a traffic accident in G-11 at Islamabad's Srinagar Highway, reported 24NewsHD TV channel on Thursday.

The ambiguity about who was driving the vehicle raised questions about the performance of the cameras installed on the motorway.

Kashmala Tariq's vehicle crashed into a Mehran car, killing four youth including three close friends Mohammad Anis, Mohammad Adil and Haider Ali alias Soni and Farooq (security guard at King Abdullah Hospital in Mansehra).

It means now there is no lead left to recognize the face of the driver.

Federal Ombudsman for Protection of Women against Harassment Kashmala Tariq denied all charges against her husband and son. 

The main reason why the camera did not identify the face of the driver was because the vehicle was e-tagged and the driver did not open his windscreen while passing through the toll plaza. 

Islamabad police have not yet reached a final conclusion as who was behind the steering.

The police have already decided to include Kashamala Tariq and her husband Waqas in the investigation. Both will record their statements in front of the investigation officer (IO).
