AN investigation is under way after a blaze at a derelict warehouse.

Firefighters were called to the Old Tannery on Hawthorne Road, in Bootle, Merseyside, at around 9pm yesterday.

At the height of the blaze, around 12 fire engines were at the scene, and there were fears that the building might collapse.

Fire crews are still damping down at the blaze, and an investigation has been launched.
