A traffic police official was run over and killed in Quetta's GPO Chowk area earlier this week allegedly by a vehicle belonging to a serving legislator, police said Friday.

The incident initially came to light when footage of the legislator's vehicle ramming into the traffic officer began circulating on social media.

Traffic Sergeant Haji Attaullah was seriously wounded in the accident and was taken to Civil Hospital Quetta for treatment where he succumbed to his injuries.

Police said the vehicle belonged to Majeed Khan Achakzai, a serving legislator belonging to the ruling coalition partners in the Balochistan government, the Pakhtunkhwa Milli Awami Party (PkMAP).

The legislator's vehicle was speeding and rammed into the traffic sergeant who was on duty at GPO Chowk, the police said.

MPA Achakzai confessed to involvement in the accident and claimed to have agreed to compensate the family members of the slain traffic policeman, Deputy Inspector General Police Razzaq Cheema said.

However, the Civil Lines Police Station lodged a First Information Report against unknown individuals.

"The law will take its course if the legislator fails to convince the family," Cheema added.

Achakzai, who was elected as an MPA for Balochistan in the PB-13 Killa Abdullah district, condemned "certain elements" who he claimed had declared him a criminal prior to a trial in court.

"We are investigating the incident", Quetta Traffic Police Chief Nazeer Ahmed Kurd told Dawn, adding that "Everything will be cleared within a few days."
