One person was arrested and five others detained in connection with the killing of Bihar BJP vice president Visheshwar Ojha, police said on Saturday.
"Harendra Singh alias Bhua Singh, named accused in Visheshwar Ojha murder case, has been arrested by the police," a statement from state police headquarters said.
Seven persons, including Harendra Singh, have been named accused in the murder case of Ojha, who was shot dead last evening at a place between Sonvarsha and Parsaura villages under Shahpur police station of Bhojpur.
Shahabad DIG A Rahman said in Ara that Singh was arrested, while five others were detained in the case.
A special team, led by Deputy Superintendent of Police Reshu Krishna, has been constituted to conduct raids to nab the accused, Rahman said.
He said on the basis of information received from the five detainees, a team had been sent to Uttar Pradesh's Balia district in search of Ojha's suspected killers.
If the named accused continue to hide from police for the next two-three days, police would request the court concerned to grant order to attach their property, the DIG said.
BJP state president Mangal Pandey had yesterday served a 72-hour "ultimatum" to the government for the arrest of Ojha's killers, failing which the party would agitate.
BJP has given a call for 'Shahabad bandh' tomorrow to protest against the killing of the party leader and alleged lawlessness in the state, party spokesperson Sanjay Mayukh told PTI.
Shahabad region comprises four districts -- Bhojpur, Rohtas, Kaimur and Buxar.
Mayukh said a delegation of the NDA would meet Governor Ram Nath Kovind tomorrow to apprise him of the law and order situation in the state.
BJP leaders Sushil Kumar Modi, Mangal Pandey, Prem Kumar, Ashwini Choubey among others reached Ojha's native village Ojhwalia in Bhojpur district to attend his funeral.
