Imran Khan: Pakistan's top court orders police to investigate shooting

The former prime minister was shot in the leg while leading his supporters on a protest march last Thursday.

One person was killed and at least 10 injured in the attack on his convoy.

Mr Khan has accused the current prime minister, interior minister and an army general of plotting to assassinate him. All of them deny the allegation.

The former prime minister has said police in Punjab province, where the attack took place, were insisting he withdrew a reference to the army officer - who holds a senior position in Pakistan's ISI intelligence agency - before they investigate his accusation.

The country's top judge wanted to know why police had not begun a formal investigation four days after the shooting - and gave them 24 hours to do so.

"If the police did not investigate, the evidence may have been destroyed at the crime scene. This way the evidence of the case will be controversial and will be unacceptable in court," said Chief Justice Umar Ata Bandial.
