How to book LTCL on trading suspended equity shares?

I purchased equity shares of a company in January 2018 and the share price declined almost to zero subsequently and its trading was also suspended in October 2019 by SEBI for non-compliance of Exchange Regulations by the company. As it is not possible to sell the shares now, how can I book the heavy LTCL(Long Term Capital Loss) of the Suspended Shares in my IT Returns? Is there a way to book the loss? The Company seems to be a fake one and there is no hope of its resuming trading in future.
