A four-alarm fire broke out Tuesday afternoon on Hull Avenue in Norwood.

The call came in just after 2 p.m. Tuesday as flames tore through three homes.

Fire officials say one person is seriously injured after trying to escape from their home. Four firefighters suffered minor injuries.

The fire began on the third floor of the middle home and then spread to the others. The top floor of one of the homes ended up collapsing.

Firefighters remained at the scene to stop flare-ups that occurred.

The Red Cross is working with all families that were displaced to make sure they have a place to stay while firefighters continue to search homes.

A cause of the fire is still unknown.
