More than 100 screws have been found scattered on a slip road next to the A40 in Carmarthenshire in what police are describing as a "deliberate act".

The screws were found in the overspill entrance to the Nantyci Showground on the dual carriageway near Carmarthen, one of the key routes out of Pembrokeshire on Thursday, February 8.

Police believe the screws were placed in the slip road to target police enforcement vehicles and have appealed for anyone with information to contact them.
