Berhampur: As many as seven persons were detained by the Crime Branch in connection with the murder of BJD leader Congress Nayak on Sunday.

Following this BJD supporters had resorted to agitations demanding an impartial inquiry into the incident. Earlier two persons named Manoj Swain and Babu Swain were arrested on February 7 and February 9 respectively by the local police in this regard.

It should be noted that Nayak was brutally murdered near his house at Haripur under Dharakote block on February 4 afternoon, following a political rivalry between two groups in the village over pasting of posters for the ensuing three-tier panchayat elections.
