Flames and smoke started billowing from the two-storey wooden structure adjacent to the main building of the Civil Secretariat minutes before the scheduled opening of the offices at 9.30 AM, officials said.
The building, which houses among other offices of the Education Department and Medical dispensary, was engulfed in flames within no time, they said.
They said it was not clear whether any employee is trapped in the building even as fire tenders are trying to douse the flames.
The cause of the fire was not immediately known
