Bhagalpur district Congress General Secretary Bipin Bihari Yadav filed the complaint against Ramdev, four officials of his Patanjali Yoga Samiti and supporters in the court of Chief Judicial Magistrate (CJM) R C Malviya yesterday, they said.
The court has fixed January 23 as the date of hearing.
In his complaint, Yadav alleged that Ramdev's "baseless" remarks against Rahul Gandhi and Sonia Gandhi made during a day-long deliberation on yogic philosophy here on Tuesday, have hurt sentiments of party workers, they said.
He also alleged that when his party workers demanded an apology from Ramdev for his "comments" on Rahul Gandhi and Sonia, the yoga guru instigated his supporters to get into a clash with Congress workers at the Bhagalpur Railway station on Tuesday evening which left four injured, sources said.
Ramdev, who visited Bhagalpur as a part of his "Sampark Samvad", had said that he would go in for extensive campaigning in Rai Bareili and Amethi against Sonia Gandhi and Rahul Gandhi for the forthcoming Lok Sabha polls.
