The accused Praveen Yadav (40) is a Delhi University graduate whose father is an ex-employee with the Delhi Transport Corporation. He was nabbed by the crime branch from Rohini on Wednesday.
Police said apart from the recent ones, Yadav's name figures in as many as 11 criminal cases post his remittal. He had walked free after serving three years of his sentence.
"A pistol, four cartridges and a Duster car was recovered from his possession. He has confessed to recently carrying out two attacks on his rivals in a period of three days," Joint CP (Crime) Ravindra Yadav said.
Within three days, Yadav attacked one Joginder Rana over a property dispute who, police said, had a narrow escape.
