READING, Pa. (AP) — The owners of a Pennsylvania cemetery are trying to prevent the relatives of those buried there from visiting the graves.

The Reading Eagle reports that a company owned by Paul and Jean Dovin filed a lawsuit in county court Monday that says the advertisement for the property failed to inform them the cemetery was active and people were still being buried there.

Relatives say the owners have threatened to call police if they visit loved ones and have warned them that flowers and flags placed on the graves will be removed.

The couple bought the property, known locally as Rock Cemetery, in 2010. The cemetery is about 40 miles west of Philadelphia and the site of an 18th century stone church.
