A major fire at a crystal factory in Belfast is being treated as suspicious, according to the PSNI.

More than 40 firefighters tackled the blaze, which broke out last night at an industrial estate in the west of the city.

Belfast Crystal is a 40-year-old business that is run by three generations of one family.

It was badly damaged with part of the roof destroyed and the owners have been left devastated, a public representative said.

A statement from the PSNI said: "The premises have sustained substantial damage as a result of this fire, which is being treated as suspicious at this time."

The Belfast Crystal factory is on Blackstaff Road in the Kennedy Way industrial estate.

Fire appliances, a high reach aerial machine and a command unit attended and the firefighting operation was "extensive", a statement from the Northern Ireland Fire and Rescue Service said.

Fire crews arrived at about 6pm and were confronted by a well-developed fire in the property.

Gas cylinders were on the premises.

Buildings including Kennedy Way Shopping Centre were evacuated. Police have appealed for anyone with information to contact them.
