Broomfield police are asking the community for help in determining why homemade, long-term pinhole cameras were placed in two open-space areas.

The first camera, found Tuesday, was adhered to a park bench in an area west of West 18th Avenue and Iris Street, according to a news release from police. The device was reported at 11:28 p.m.

The second camera, discovered Wednesday, was affixed to a fence in the open-space area northwest of Ridgeview Circle and Kohl Street after a call from a resident at 8:42 p.m.

The cameras were made using a sealed can with a small hole and photographic paper inside, the release states.

No charges are pending in the matter, but police would like the owner to confirm that the cameras are not a threat to the public.

Broomfield police are asking the owner to contact Detective Mike Svela at 303-438-6400.
