The three gang members -- Deepak (22), Kamal Thapa (22) and Farman (19) -- were arrested from Anand Vihar ISBT when they were planning to leave for Nepal, Deputy Commissioner of Police (East) Rishi Pal said.
Rs 53.91 lakh in cash were recovered from them, he said.
A complaint of theft of Rs 25 lakh was lodged by financier Mony Agarawal at Lahori Gate police station on June 27.
"During interrogation, it was revealed that Kamal worked as a collection agent for Agarwal and knew the movement of cash through hawala and planned to steal the money thinking that their employer will not register a complaint of theft of the unaccounted money," said the officer.
