The sisters were arrested in Lahore over the weekend under a warrant issued by the city's deputy commissioner, accusing them of mobilising supporters 'through social media and public meetings' and creating a 'law and order situation', according to a police official who confirmed the detentions to the BBC.
Their lawyer confirmed on Monday that all three are now in Kot Lakhpat jail in Lahore, detained for 30 days. A spokesman for Khan's Pakistan Tehreek-e-Insaf (PTI) party described the arrests as 'illegal detention' and called for their immediate release.
Aleema Khanum's son, Shahrez Khan, posted on X demanding the government 'disclose her whereabouts and ensure her safe return'. Earlier, the family said they had 'no contact or news of her whereabouts'.
The arrests are widely seen as an attempt to suppress dissent ahead of PTI-organised protests scheduled for 27 September, when demonstrators plan to march on Islamabad. Streets in the capital are already lined with shipping containers to safeguard government buildings. Pakistan's interior minister has been quoted in local media as saying the protests 'harm the country' and that the government will 'do everything they can to stop them'.
Imran Khan has been in detention since 2023. His party and family say the government is 'slowly killing' him in prison.
