ISLAMABAD, Dec 26: An unexplained gunfire by one of the Frontier Constabulary (FC) personnel deployed at the Swedish embassy led to their replacement on Monday.

The four-man security staff was immediately shifted to the Diplomatic Enclave and an investigation ordered to ascertain whether the gunfire was accidental or deliberate.

Sources said the SMG of guard commander Naeem Khan accidentally went off in the FC tent outside the embassy at Sector F-6/3 due to mishandling and negligence. At the time of the incident, two other FC personnel were preparing meal inside the tent.

The bullet made a hole in the tent about two to three feet above the ground, they added.

Senior officials from the FC and Kohsar police reached the spot and seized the weapons.

The security in-charge of the Swedish embassy met the officers and showed his reservation over the incident. In response, the four-member security team was replaced with other FC personnel.

A senior police officer, however, said one of the FC personnel, Naeem Khan, was behind the gunfire after exchanging harsh words with his colleague Abid Hussain outside the embassy.

“After the heated argument, Abid went into a bunker while Naeem moved to the tent and fired a single shot into air,” he added.
