Vandals have broken the windows of a North Yorkshire church in the fifth attack in the past four months.
Police in Catterick Garrison are appealing for witnesses after 20 panes of glass were smashed at the St Joan of Arc Roman Catholic Church.
The church has had a number of windows broken in a series of attacks that started in December 2011.
North Yorkshire Police said they had increased patrols in the area and were conducting house-to-house inquiries.
The church is located just outside the town's military base.
PC Nicola Pattinson, of Catterick Garrison Safer Neighbourhood Team, said: "Unfortunately some mindless acts of vandalism have occurred at the church over the past few months which has caused a great deal of upset and inconvenience to the people who run and use the premises. I am appealing to local residents to let the police or Crimestoppers know if they have seen any suspicious activity in the area or if they know who is responsible for causing the damage."
