A FIRE at the University of York was accidental but its cause is unlikely to be determined for a month, a spokesman for North Yorkshire Fire and Rescue said.

Hundreds of people were evacuated as firefighters tackled a major blaze at the chemistry department in Alcuin Way on February 2.

Eleven fire crews and an aerial ladder platform were sent to the scene as firefighters opened up a large area of the roof as they tackled the flames This week work has been under way to stabilise the building due to possible asbestos and structural damage before assessments could begin as to the cause of the fire and the extent of damage caused.

A fire investigation officer is currently working on a report about the cause of the fire and its findings should be available in a month's time.
