Harish (24), along with his three accomplices, had opened fire on his uncle over a family dispute in the wedding ceremony of his sister on January 30. The victim sustained bullet injuries, a police official said.
Acting on a tip-off that the accused would meet his accomplices near a metro station in South west Delhi, police laid a trap and arrested Harish, the official said.
"During interrogation, Harish has confessed to his involvement in the crime," police claimed.
