Police are trying to track down a man who spent three hours licking a doorbell at a California home. Surveillance cameras caught Roberto Daniel Arroyo in the act. The homeowners were not home at the time, but their children were inside the house sleeping. Police said a newly installed surveillance system helped them investigate the case. The security cameras also caught Arroyo moving an extension cord to the front yard and relieving himself. Police said Arroyo could face misdemeanor charges of petty theft and prowling.
