AN arson investigation unit is looking into a fire which severely damaged a house.

For a crew attending yesterday's blaze in Granville Road, Grangetown, it was their second visit to the scene. Hours earlier they put out a rubbish fire outside the house.

The second fire, which broke out in the early morning, devastated the ground floor and caused severe fire, heat and smoke damage to the first floor.

Smoke also filled the house next door.
