Police said a drunk Iowa City man couldn't tell officers what he had been up to Saturday night.

Or, more importantly, why he didn't have any clothes on.

Around 11:30 p.m. Saturday, Iowa City police officers took a complaint of a naked man walking around the area of 1100 Jefferson St. Police found the man, 55-year-old Alan J. Ryan, asleep on the porch of a Jefferson Street residence.

Police said Ryan woke up as officers approached. He smelled of alcohol, was unsteady and disoriented and refused a breath test, police said.Ryan found his clothes and was placed under arrest. Police said he could not offer an explanation for where he had been earlier in the night or why he was walking around naked. He was charged with public intoxication, a simple misdemeanor.
