The Congress leaders were squatting right in front of the main gate of City Kotwali police station since yesterday demanding that MP BJP Chief Nandkumar Singh Chauhan should be booked for "connecting" Bhuria's son Dr Vikrant to Rajendra Kasawa, prime accused in the Petlawad blast here which left 89 people dead and nearly 100 injured last week.
They were produced in the court of area Sub Divisional Magistrate (SDM) Syed Ashfaque Ali, who released them after some formalities, the police said.
However, Bhuria said that Congress leaders and workers will continue their protest till Nandkumar was booked.
"Nandkumar has told media in Bhopal that Kasawa was a close friend of my son Vikrant, which is totally baseless. My son does have a friend named Rajendra Kasawa, but he is 30- years-old and lives in Jhabua town, not in Petlawad," Bhuria said.
The September 12 explosion in New Bus Stand area of Petlawad here completely destroyed two buildings -- the one in which the explosive material was stored, and adjacent building housing Sethia restaurant -- besides damaging several houses.
The residential building in which the explosion took place is owned by Kasawa, who reportedly has a licence for use of explosives in digging of wells.
Yesterday, investigators grilled Rajendra Kasawa's wife Pramila (45) and son Shubham to get clues about his whereabouts.
A case under section 304 (culpable homicide) of IPC and the Explosive Substances Act has been filed against Kasawa.
