The incident occurred when the youth, who incidentally goes by the name of Nitish Kumar, came to meet the CM and hand over his request at 'Janata ke Darbar mein Mukhya Mantri' programme.
As the accused, a resident of Arwal district bent down to take off his chappal, he was immediately caught by a posse of security men.
Senior Superintendent of Police Manu Maharaj told reporters the youth has been arrested and taken to Sachivalaya police station for detailed questioning, the SSP said.
It emerged that the youth had created ugly scenes earlier too at the 'Janata Darbar' programme of senior BJP leader and former deputy chief minister Sushil Kumar Modi recently.
The grievance of the youth was not very clear but officials said he was apparently angry over the state government's recent advisory against use of fire for cooking and hawan etc between 9 AM to 6 PM to curb increasing incidents of fire.
