Differences have emerged among the members of a joint investigation team (JIT) tasked with probing the attack on former prime minister Imran Khan, 24NewsHD TV channel reported Tuesday.

The differences emerged after Capital City Police Officer (CCPO) Lahore Ghulam Dogar — who is leading the probe — has assigned the key responsibility of interrogating the suspect to anti-corruption officer Anwar Shah and no other member of the probe panel is given access to the attacker.

The four members of the JIT have shown differences and shared their reservations with the Home Ministry and Punjab Police chief.

They have written a letter to the Home Department highlighting the problems.

The JIT members who expressed concerns are Khurram Shah, Naseebullah, Ehsanuullah and Malik Tariq Mehboob.

The Pakistan Tehreek-e-Insaf (PTI) chairman was attacked on November 3 in Wazirabad while he was leading the “Azadi March” against the Shehbaz Sharif-led government demanding snap polls.

The law enforcement agencies (LEAs) apprehended suspect Naveed from the crime scene — who also confessed to opening fire on the PTI leadership. A first information report of the incident was registered on November 7 under the Anti-Terrorism Act 1997.
