Amir Khan had launched a mobile gaming application named E-Nuggets, which was designed for the purpose of defrauding the public.

During the initial period, the users were rewarded with commission and the balance in the wallet could be withdrawn in a hassle-free manner, which provided initial confidence to them and they started investing bigger amounts for greater percentage of commission and a greater number of purchase orders.

After collecting handsome amounts from the public, all of a sudden withdrawal from the said app was stopped on one pretext or the other. Thereafter, all data, including profile information, was wiped out from the said app server.
