Additional District and Sessions Judge (First Class) Bipin Bihari rejected the petition of the Nawada Lok Sabha candidate of the saffron party.
Earlier on April 23, Sub-divisional Judicial Magistrate Amit Sekhar had issued the warrant against the former Bihar minister.
The warrant was issued in connection with an FIR filed against Singh on April 21 alleging that he had said in an election meeting under Harla police station on April 18 that those who opposed BJP's Prime Ministerial Candidate Narendra Modi would have to find a place in Pakistan.
Earlier on April 25, he got an anticipatory bail by Patna District and Sessions Judge Birendra Kumar on an FIR on the same charge.
