Mr Fatah was not in Delhi. The gangster's aide was in the city on a reconnaissance mission, Mr Kushwah said, adding a pistol and four live cartridges were found with him. Mr Chaudhary was arrested in June last year along with three others. Police said they found weapons and "hawala" money sent by Chhota Shakeel, but was released on bail within four months.
Police said they had been planning to kill Hindu Mahasabha chief Swami Chakrapani at that time. He allegedly contacted Chhota Shakeel again. But after his bail was cancelled, he was sent to Tihar Jail in New Delhi.
After he was again released on bail, he got in touch with Chhota Shakeel, police said, adding Mr Chaudhary then started carrying out the gangster's Delhi-based activities. He is being interrogated, they said.
