The sources said the ED conducted a search related to an alleged money laundering case.
In September last year, Amanatullah Khan was arrested by the Anti-Corruption Branch (ACB) of Delhi Police in a case related to alleged irregularities in appointments.
This action came days after the ED arrested AAP leader and MP Sanjay Singh after raids at his residence and questioned him over 10 hours in a case linked to the Delhi liquor policy.
