Two officials of a private construction company were shot dead in Bihar's Saran district by unidentified gunmen, police said on Friday.

"A manager and a munshi (accountant) were killed in Bhagwanpur late on Thursday night when they were sleeping in a base camp office," a police official said.

The private company is engaged in road construction.

The district administration of Saran was also investigating the incident.

The police were unable to ascertain the reason behind the attack.

"We are looking at all angles, including demands of rangdari (unofficial tax) by criminals from such construction companies," the official said.
