Mumbai Police lodged a First Information Report against actor Imran Khan, his partner Lekha Washington, and a number of others after they were taken into custody at August Kranti Maidan on Saturday, 10 October, in connection with a protest held there. People gathered in the streets for a rally expressing solidarity with a demonstration the Cockroach Janta Party (CJP) had organised in Delhi, where the party had called for Chief Election Commissioner Gyanesh Kumar to vacate his post.

Charges laid out in the FIR — filed at Gamdevi police station — draw on Sections 223, 126(2), 189(2), 189(3), and 189(5) of the Bharatiya Nyaya Sanhita, media reports indicate. Three legal provisions anchor the matter: one addressing non-compliance with directives from public officials, another covering unlawful physical restraint, and a third tied to participation in an unauthorised gathering.

A formal complaint lodged by officers on duty followed the event, which unfolded in an area where substantial security measures had been put in place beforehand. Prior to the event's scheduled start, police cordoned off streets surrounding August Kranti Maidan and deployed additional personnel to prevent the assembly from going ahead. People in the area were taken into custody while a security presence was kept in place nearby.

Tallies from the demonstration in Mumbai varied across sources, with one set of figures placing those taken into custody at upwards of 400 and another putting the citywide total closer to 600. Among those taken into custody were Imran, Lekha, and a relative of Imran's named Zayn Marie Khan. Hours after the initial detention, the group walked free.

After being taken into custody, Imran photographed himself inside a police vehicle and posted the image on Instagram. He posted the image alongside the caption "Apparently I'm going for a drive," while Lekha continued posting updates to her social media accounts in the period following her detention. Where the transfer was taking them, she said, was not something she had any way of knowing.

Following her release, Lekha told reporters that police had not permitted them to go back to their homes or to arrange any form of transport. A post to her followers confirmed that the group had made it through safely and were heading back.

Gatherings in Mumbai took shape as an act of support for the CJP-led action unfolding in Delhi, where authorities took a number of participants into custody. Calls for Gyanesh Kumar to step down have centred on questions about how electoral rolls were revised.

The filing of the FIR has brought Imran, Lekha, and the others named in the matter into formal legal proceedings, a development that follows the demonstration held on Saturday. No further details about the case or any follow-up police action had been made available at the time of reporting.
