Arsonists set fire to an empty house twice in one night, putting the lives of a family next door at risk, firefighters have warned.

A house in Holme Wood Road, Bradford, was attacked at 12.45am this morning and at 1.30am. A window was broken and accelerant and fireworks used to start a fire. Matches and a body spray can, which fire officers suspect had been used as a blowtorch, were found. Police are investigating.
