Vandals have caused more than £20,000 of damage to a former nightclub.
The yobs threw bricks and rocks at The Edge on Preston Street in Kirkham, leaving extensive damage.
Five large double-glazed windows were ruined in the smashing spree, which took place sometime between 9am on Wednesday, May 2 and 9am on Bank Holiday Monday May 7.
The former nightclub has been closed for about a year.

“This amount of damage is very unusual in Kirkham and if anyone knows anything that could assist us with our investigation I’d urge them to please contact Kirkham Enquiry desk on 01253 604734.”
