KARACHI: A Swedish-Pakistani man, who allegedly killed a policeman in the southern Pakistani port city of Karachi, fled Pakistan in the wee hours of Tuesday, police officials said. 

The suspect, Khurram Nisar, shot dead Abdul Rehman, a member of Shaheen Force that tackles street crime in Karachi, in the city's Defence Housing Authority (DHA) area late Monday, following a heated exchange of words between the two.

Nisar, who came to Karachi three months ago, is the son of a former deputy commissioner and lived near the site of the shooting, according to Deputy Inspector General (DIG) Irfan Baloch. 

"The suspect involved in the murder of the policeman will be brought back," DIG Baloch said in a statement Tuesday night. 

"Will contact the Interpol for the extradition of the suspect." 

CCTV footage of the shooting, widely shared on social media platforms, shows the suspect and the policeman stepping out of a black car, with weapons drawn and arguing with each other.

Asad Raza, a senior superintendent of police (SSP), told Arab News that Rehman and another cop accompanying him had stopped the car and the suspect opened fire on one of the two armed policemen as they engaged in an argument. 

Ameen-ul-Haq, the colleague of the deceased cop, said he and Rehman were patrolling the area when they heard cries of a woman in a passing car. They chased the car and stopped it near Abdullah Shah Ghazi shrine in Clifton area, according to the first information report (FIR) of the incident.

It was then that Rehman ran, got into the suspect’s car and sat in the front seat. The woman disembarked from the car and fled the scene, while the suspect sped away the car. Nisar shot Rehman dead after they both stopped and disembarked in DHA Phase-5 area.

The deceased cop, who hailed from Buner town of Pakistan's northwestern Khyber Pakhtunkhwa province and resided in Karachi's Railway Colony, was to tie the knot in December, his brother told Arab News.

Parents of the suspect earlier told the police they had no idea of their son’s whereabouts, according to local media reports.  

They said their son visited Pakistan once a year and they did not know what he did when he visited his home country, neither they could take any responsibility for his actions.
