Congress leader Imran Masood was today stopped from meeting Bheem Army founder Chandrashekhar Azad, who is lodged in the district prison here.
The jail authorities cited an administrative order as the reason for their refusal to let Masood meet Azad.
"Only the relatives of Chandrashekhar can meet him," said Additional SP Prabal Pratap Singh.
Masood protested the move, and called it "violation of fundamental right".
Masood had earlier voiced his support for Azad who was nabbed from Dalhousie area of Himachal Pradesh last week.
Thirty-year-old Azad, the main accused in the Saharanpur caste violence, had been on the run for nearly a month and carrying a reward of Rs 12,000 on his head.
