Milk bottles destined for staff and pupils at a primary school were filled with cleaning products, police have revealed.

The two half-empty bottles of milk were left in fridges and were discovered by a member of staff on Monday morning after being tampered with. Analysis of the bottles confirmed they were filled on the school premises with a cleaning product.
No milk was given to any staff or pupils and no threats have been made.
