Additional Director General of Police (Headquarters) Gupteshwar Pandey told PTI that the explosion took place around 11:30 AM when a van carrying under-trials for production in the court entered the premises and they were being taken to the court lock-up.
The woman, suspected to be carrying the explosive, was aged about 35-40 years, the ADG said, adding there was a possibility that she could be a human bomb.
Pandey, however, ruled out the possibility of the blast being a terror attack.
A police constable Amit Kumar (40) was the other person killed, he added.
Bhojpur District Magistrate Pankaj Kumar Pal said that about 16 people, including three lawyers and as many policemen, were injured and taken to the civil hospital.
The DM and Superintendent of Police Akhtar Hussain have reached court premises, the ADG said, adding Inspector General of Police, Patna, A K Ambedkar is on the way.
The district administration has sealed the court premises.
Lawyers and eyewitnesses said, the woman was sitting between the van parked near the gate and the court lock-up which was about 8-10 feet away.
As the undertrials were being taken from the van to the lock-up one by one, the bomb exploded, they said.
