Police took Manvi into custody at the nomination site and moved her to the Gandhi Maidan police station, according to Aaj Tak. Speaking after her arrest, Manvi alleged that a political conspiracy had been engineered against her, though the specific grounds for the arrest were not detailed in the initial reporting. Her daughter has separately made serious allegations against unnamed political leaders in connection with the episode, though the substance of those allegations was not immediately available.

Manvi, a Patna-based social activist and president of the Mahila Vikas Manch, was named as the JJD's candidate for Bankipur on July 1 by party president Tej Pratap Yadav, the expelled former RJD leader and Bihar's former state minister who launched the party after his removal from the RJD by his father, Lalu Prasad, last year. Announcing her candidacy, Yadav had described Manvi as someone who had worked hard for the constituency in her capacity as a social worker, and noted she came from the Vaishya community — a group he said the BJP had long courted, positioning her as a deliberate counter to the ruling party's traditional base in the seat.

The Bankipur seat fell vacant after sitting MLA and BJP national president Nitin Nabin was elected to the Rajya Sabha. Nabin had held the seat for five consecutive terms, most recently winning by a margin of nearly 50,000 votes in the 2025 assembly election, making Bankipur a long-standing BJP stronghold. The bypoll has already drawn other high-profile contenders, including Jan Suraaj Party founder Prashant Kishor, who is contesting the seat himself in what he has called a referendum on the state government. The BJP had not finalised its own candidate as of the last update, with names including Ajay Alok and Neel Ratan Ghosh reportedly under consideration.

Manvi's arrest, coming on the day of nominations, adds a volatile new element to what was already shaping up as a closely watched three-cornered contest. Neither the Patna police nor the JJD had issued a detailed statement on the reason for her arrest at the time of publishing, and further details on both the charges involved and her daughter's allegations remain awaited.
