ISLAMABAD: Pakistan’s High Commission in New Delhi lodged an official protest with the Indian government on Monday night after its first secretary Zargham Raza was reportedly manhandled by an unidentified mob.

According to details gathered so far, Raza was manhandled by a group of unknown motorcyclists when he was busy shopping in the evening. Both Raza and his driver reportedly sustained injuries in the attack.

According to diplomatic sources, Islamabad has urged a probe into the matter and also demanded the Indian authorities to increase security of the Pakistani staff stationed there.

“Our first secretary and his driver both of whom sustained serious injuries have been provided medical treatment and an FIR (police complaint) has also been lodged,” Aizaz Ahmed, Pakistan's foreign office spokesman was quoted by NDTV.

Officials in the Indian foreign ministry and Pakistani authorities were not immediately available to react to the press reports.

According to another Hindi-language news channel, Raza did not suffer any serious injuries.

Relations between the two countries have been fractious in recent weeks, with both sides protesting at the deaths of prisoners held by the other's government.

The latest incident comes after the murder of Indian prisoner in a Pakistani jail, which was followed by the murder of a Pakistani prisoner in an Indian jail last month.
