A man reportedly smeared poop on a random woman's knife, bedding and carpet after forcing his way into her apartment in downtown Austin this week.

Robert Brantner, 43, was charged with criminal trespass Friday after he went into the unit of a woman who said that she'd left her door unlocked because she expected people and that only residents on the floor were supposed to have access, according to an arrest affidavit obtained by The Austin American-Statesman.

The woman didn't know Brantner, who's described by the Travis County Sheriff's Office as transient, and said she started screaming for him to get out.

Although he apologized, he didn't budge. The woman pushed him out of the way as she ran screaming out of the apartment, The Statesman reports.

Brantner pursued her, saying that he was sorry and that he had the wrong place. He tried opening the door of another apartment, but when it wouldn't open, he returned to her apartment and locked the door, the affidavit states.

"What's going on?" Brantner asked officers, who'd been telling him to come outside for 10 minutes. He was wearing just a towel and was wet from a shower.

They then arrested him and found the feces he'd wiped in several places.
