A 46-year-old woman was charged Saturday with punching a police officer who told her to stop urinating in public in Waikiki, according to police reports.

Athena Johnson, of no local address, was charged with first-degree assault on a law enforcement officer. She remained at Oahu Community Correctional Center today, unable to post $40,000 bail and had a preliminary hearing scheduled for Wednesday.

Johnson urinated on Kuhio Avenue next to a police-subsidized vehicle with an illuminated blue light on top about 10 p.m. Friday, according to a police affidavit filed in Honolulu District Court on Monday.

A sergeant sitting inside the parked vehicle saw Johnson step into the road next to the passenger side of his vehicle, and he got out to see Johnson squatting and urinating on Kuhio Avenue, the affidavit said. The officer told Johnson to stop urinating, and she became hostile, shouting threats and obscenities, and eventually struck the officer with a fist on the left side of his head, the document said. The officer felt pain, and the two struggled on the ground. At some point, he called for back up.

Johnson continued to resist and kick after other officers arrived, scratching another one and spitting on a third, the affidavit said.

She was arrested near the Food Pantry for several offenses, including harassment, urinating in public, and assault on a police officer.
