Pakistan's former prime minister and PTI Chairman Imran Khan has been summoned by a joint investigation team (JIT) over the attack on the Lahore Corps Commander House (Jinnah House) on May 9.

The JIT has called Khan to appear before them at the Qilla Gujjar police headquarters on Tuesday at 4 pm, reports Dawn.

The summons is in connection with a case registered against the attack at the Sarwar Road police station.

Imran Khan has been accused of abetting the attackers who vandalized and set fire to the Jinnah House while he was in prison. 

“Imran Khan is required to attend the office of the DIG Investigation to join the investigation proceedings entrusted to the JTI formed by the Punjab government, reads the summon notice, issued by Lahore DIG (investigation) Kamran Adil.

Lahore police chief Bilal Siddique Kamyana has confirmed the summoning of the PTI chief for questioning.

The former prime minister will be interrogated to determine the extent of his involvement in the attack.

Several other senior PTI leaders and activists have also been named in the FIR.

The decision to summon Imran Khan came after Lahore SSP (investigation) Dr Anoosh Masood visited Kot Lakhpat jail where PTI leader Dr Yasmin Rashid and fashion designer Khadija Shah, who was arrested in connection with the attack, are being held.

This visit followed Imran Khan's accusations against the caretaker Punjab government of mistreating PTI's imprisoned women supporters.

Imran Khan had made unverified claims of the rape of PTI women political prisoners. “I have heard about the rape of PTI women political prisoners,” he said.
