Nineteen gravestones have been vandalised in a section of a Leeds cemetery used by Muslims.
One headstone was broken and a number of name plaques on wooden stands were damaged at Harehills Cemetery.
Police said they were "keeping an open mind" on whether the graves were deliberately targeted because they were linked to Muslim families.
The damage is believed to have happened overnight last Thursday. Witnesses are being asked to contact police.
Insp Nik Adams said: "This incident has caused a great deal of upset and distress to a number of people in the local community.
"Over the weekend we have worked alongside community and religious leaders to identify and contact the next of kin of those whose graves have been affected by this mindless vandalism.
"At this stage in the investigation we are keeping an open mind on whether the graves were deliberately targeted because they were linked to Muslim families or whether they were vandalised because of their proximity to a nearby path and two thoroughfares that run through the cemetery."
