Police monitoring the ongoing protests in Portland weren't quite ready for 'Naked Athena'. That's the nickname given to an unidentified woman who confronted the cops wearing a facemask - and nothing else.
The woman stood in front of a line of heavily armed officers, striking a series of yoga and ballet-style poses.
Her birthday suit strategy seemed to work - witnesses say the officers left about 10 minutes after Naked Athena's arrival.
Portland has some of the nation's most lenient laws on public nudity, recognizing it as a legitimate form of political protest.
