Dhaka, Nov. 6 -- Police are relying on CCTV footage to find those who hurled petrol bombs at two government offices in Chattogram's Sholoshahar under cover of darkness.

The bombs were thrown from a flyover at the Local Government Engineering Department (LGED) building and the Chandgaon land office after 8:30pm Thursday.

Two bombs thrown at the LGED building shattered on the ground without catching fire. The one thrown at the land office burst into flames, but cleaners put it out and dumped it in a drain.

No damage was reported. Police are treating the attacks "seriously".

The Karnaphuli Gas Distribution Company Limited (KGDCL) office, Chattogram education board and Sholoshahar Railway Station are near the scene.
