Officials said they suspect a fierce thunderstorm that rolled through Connecticut this week is believed to be the cause of a house fire in Hamden.

Hamden fire crews responded to an apartment complex late Tuesday due to multiple reports of a lightning strike. Firefighters found the roof smoldering and charred in places.

Two apartments sustained water damage and the residents have been relocated to local emergency housing. The Connecticut chapter of the American Red Cross is assisting relocation efforts.

No injuries were reported. Fire investigators are continuing the investigation.
