There are supposedly 8 million stories in the “Naked City.” Add one more.

Butler police on Saturday arrested a Center Township man after he allegedly broke into a city apartment wearing nothing but his birthday suit.

Not surprisingly the victim had no trouble identifying the suspect — a one-time boyfriend, according to court documents.

Matthew Fitzpatrick, who turned 41 years old the day before, was arraigned on charges of burglary and indecent exposure, and released on his own recognizance.

Fitzpatrick is accused of forcing open the front door of Stephenia Johnson’s home in the 300 block of West New Castle Street shortly after 3 a.m. Saturday.

When the 36-year-old Johnson notified authorities, she reported there was a nude dude in her apartment. She was in bed at the time. Her 7-year-old son also was at home.

Johnson told investigators that she and Fitzpatrick were on-again-off-again girlfriend-boyfriend. For the past month, police said, the two had been off again.

A preliminary hearing in the case was not immediately set.
