Brad Chen, 26, was last seen in Ewa Beach, Oahu, leaving his residence to go to a local park and never returned. He was reported missing the following day after failing to contact family; the Honolulu Police Department is investigating and asking anyone with information to come forward.

Chen is described as Asian, 5 feet 10 inches, about 190 pounds, with brown hair and brown eyes. Notable tattoos include a band on his left bicep and another on his right forearm. He was last seen wearing a white tank top, red shorts and brown shoes, and he left on a black e-bike that has not been located. Authorities say he has a health condition that requires medication, which adds urgency to the search.

Anyone who saw Brad on the day he disappeared, saw a black e-bike matching that description, or has other information is asked to contact the Honolulu Police Department.
