The criminal mind can be cunningly brilliant—or stunningly foolish. You can safely put Emma Way of the U.K. into that second category. She’s the aggressive 21-year-old motorist who allegedly hit a cyclist while out for a drive in the city of Norwich, fled the scene, and bragged about it on Twitter on Monday.

“Definitely knocked a cyclist off his bike earlier—I have right of way he doesn’t even pay road tax! #bloodycyclists,” she tweeted.

Her admission was soon retweeted more than 300 times, inspiring angry responses and the nickname “twit and run girl” by fellow Twitter users. They also retweeted her brag to the social-media savvy Norfolk police department, who wrote back, "we have had tweets ref an RTC with a bike. We suggest you report it at a police station ASAP if not done already & then dm us." Though Way deleted her account, the ball kept rolling. The cyclist, Toby Hockley, a chef who had been taking part in an organized ride, came forward, and police said they tracked down Way and are progressing with an investigation.

On Wednesday, the police department told Yahoo! Shine there was “no further information at this time.” Way later apologized on ITV News, saying "It was a spur of the moment thing and I'm sorry," adding, "I don't want any cyclist to think I have hatred against them." Her lawyer said during the interview that she'd been interviewed by police but that no arrest had been made.

Way, unfortunately, is not alone in bragging about wrongdoing on her smartphone. The post-privacy generation has given way to a host of accidental confessions and video-taped self-indictments. Get a load of these other social-media users outed by their own Internet mistakes:
