KENNEBUNK (NEWS CENTER Maine) — A man from Dover, New Hampshire allegedly impersonated a police officer at a playground in Kennebunk.

Kennebunk Police say 30-year-old Ryan Calista sped to a parking lot at the playground on Park Street wearing a police hat and vest, and told people he was an officer looking for a missing 13-year-old boy on Wednesday afternoon, November 7.

Witnesses told police Calista's truck was equipped with flashing blue lights, and several adults who were present became suspicious when the Calista refused to identify himself or give his name.

Witnesses took photos of Calista and his truck before he left the parking lot.

The Dover man was arrested around 6:30 p.m. Wednesday after Dover police said he was impersonating an officer in New Hampshire as well.

Calista has outstanding arrest warrants. He is due in Biddeford District Court on February 20, 2019.

The Kennebunk Police Department are reminding residents that police officers, even dressed in plain clothes, will still have their badges displayed, and will readily show their credentials if there is any doubt about their identity.
