Enforcement Directorate on Thursday attached the property of self-proclaimed "scientist and doctor" Munir Khan, earlier arrested on the charges of cheating and forgery.
"We have attached property worth Rs 6 crore," an ED official said.
Khan, arrested in May 2010 and later granted bail, is accused of cheating over 120 persons, by claiming that his medicine `Body Revival' can cure all diseases, including cancer. He had netted some celebrity clients, police said.
A 100 ml bottle of the medicine sold for Rs 16,000. TV advertisements featured Khan with yesteryear television actor Tabassum.
Tabassum has filed intervening application in the court, saying that Khan misled her into endorsing the product on TV.
In 2009, Khan's clinic at suburban Versova had been raided by the Food and Drugs Administration officials.
He has been booked under relevant sections of Indian Penal Code, Drugs and Magic Remedies (Objectionable Advertisements) Act and Maharashtra Medical Practitioners Act.
