Police intercepted a car last night at a barricade on Mother Teresa Crescent Road near Patel's residence.
A senior police official said the youth was talking about becoming President of the country. "He was mentally disturbed. We took him to a nearby police station.
"We also checked his car and recovered a pistol and 21 live cartridges. He had licence for pistol. He also did not tell us why he was carrying a pistol and also did not tell us where he wanted to go," the official said.
