On Monday, the Supreme Court (SC) refused to grant anticipatory bail to Khan, the 50-year-old legislator from the Okhla assembly seat, in the case.
A top court bench of Justices Sanjiv Khanna and Dipankar Datta asked the AAP leader to appear before the anti-corruption agency on April 18 at 11 am.
This comes as another blow to the after Delhi Chief Minister Arvind Kejriwal was arrested by ED less than a month ago in the liquor policy case.
The money laundering case against Khan is based on a Central Bureau of Investigation FIR and three complaints from Delhi Police.
According to the CBI's allegations, Khan acquired huge proceeds of crime in cash by engaging in unlawful staff recruitment at the Delhi Waqf Board, and then using the mobey to procure real estate assets under his associates' names.
The ED also alleged that illegal staff appointments took place at the Waqf Board, leading to personal gains through unauthorised property leases during Khan's chairmanship from 2018 to 2022.
