Anchorage Police are investigating reports of a partially-naked man spotted near the Westchester Lagoon on Tuesday. 

Two separate reports were made Tuesday to APD about seeing the man in the park on the east side of Minnesota Drive, across from Westchester Lagoon. Officers responded but were unable to locate the man. 

APD spokesperson Renee Oistad says the circumstances surrounding the man's behavior suggest he is suffering either from mental illness or perhaps drug use. No sexually-related behavior was reported. 

The man was described only by witnesses as a light-skinned or mixed-race black male. 

If you have any information that may assist officers in this case, you're asked to call APD.
