LOUISVILLE, Ky. (WDRB) -- Louisville Metro Police say they've arrested a man who was somewhere he wasn't supposed to be, pretending to be someone he wasn't.

According to an arrest report, officers were called to University Hospital, near the corner of S. Jackson St. and E. Chestnut St., shortly after 6 p.m. on Wednesday.

When officers arrived, hospital security allegedly told them that 52-year-old Patrick Andrew Campbell was found inside an employee-only elevator on the 8th floor.

Police say Campbell had several ID badges attached to his shirt, and gave police a false date of birth. Officers eventually discovered the accurate information and confirmed -- via a national database -- that Campbell had used several aliases in the past.

Campbell was arrested and charged with criminal trespassing and giving officers a false name or address, according to an arrest report. Both are misdemeanor charges.

His reason for being in the hospital is not clear.

Police say it's not the first time Campbell has been found in a hospital. Last month, they say they arrested Campbell, who was allegedly found at another hospital wearing a labcoat, scrubs and a face mask.

That incident took place at Norton Hospital at the corner of E. Chestnut Street and S. Brook Street.

Police say they were called to the hospital after security found Campbell dressed as a member of hospital staff, despite the fact that he didn't work there, either.

When police confronted Campbell, he allegedly told them that he was homeless, "so he found a bed on the 1st floor in a secured area and stayed at least one night."

Police say he wore the uniform, "so as to appear that he belonged there."

Hospital security employees allegedly told police that they found Campbell using a computer, but hospital officials tell us it did not contain any patient information.

Campbell was arrested in that incident as well.
