On Friday, the Islamabad chief commissioner constituted a JIT, and assigned SP Police Investigation, Islamabad as the team's convener.
However, Ahmeduddin Dawar — SP Dawar's brother — said he "reject[s] the JIT formed in Pakistan."
"My brother went missing from a sensitive city, and his body was found in Afghanistan," he said, adding that the case does not involve "a single country but two countries".
"And when two countries are connected then the decision should also be made at an international level," he added. "Due to the nature of this case, an international JIT should be formed to [investigate this]."
Meanwhile, KP Inspector General of Police Salahuddin Khan Mehsud paid a condolence visit at the family's Hayatabad residence and expressed the hope that Islamabad police would be successful in solving the case.
He cautioned that patience in this time is of utmost importance and that people should wait for the results of the police investigation.
IG Mehsud said that while it was not within his authority to comment on an international probe, since it was a matter under federal jurisdiction, he felt confident that the JIT would give conclusive results soon.
"I was in constant communication with the Islamabad police since the day of the abduction," the senior official said, adding that the capital police was investigating the matter from the outset.
He said the KP police will extend all possible assistance to the investigation team.
SP Dawar, chief of Peshawar police’s rural circle, was kidnapped in the G-10/4 area of Islamabad on October 26. On Nov 13, his body was found in a remote area of the Afghan province of Nangarhar and a day later, the Foreign Office said that Afghan officials had confirmed that the tortured body found was indeed that of Dawar.
Following a two-day delay and hours-long negotiations on Thursday, the Afghan side had reluctantly handed over the body of the officer of Peshawar police to his family. The issue of handing over of the body of SP Dawar flared up a diplomatic row as government officials accused the Afghan side of playing politics over a body and delaying its handover.
