Two Grade I listed churches have had their ornate stained glass windows smashed in the past week by people throwing stones.
A stained glass window in the 14th century St Andrew’s Church, in Church Street, Billingborough, was broken between Friday and Sunday.
And last Wednesday church volunteers at the neighbouring 13th century St Andrew’s Church in High Street, Horbling, discovered about 12 triangular panels of glass and three stained glass panels had been damaged by gravel from the churchyard being thrown through the window.
The window dates back to the 1930s and was dedicated by the Smith family from Horbling.
Both incidents have been reported to the police.
Anyone with information should contact police on 101, quoting incident 251 of April 21.
