A BLAZE near a 700-year-old Flintshire castle was started deliberately, fire chiefs have concluded.

North Wales Fire and Rescue Service was called to the scene, near Caergwrle Castle, at about 5.30pm on Tuesday.

Two crews attended and used beaters and a hose to extinguish the flames.

The incident was declared over just after 7pm.

A spokesman has now confirmed the damage involved 2,500 square metres of grass and the cause was confirmed to have been deliberate ignition.
