Hell may hath no fury like a woman scorned, but you wouldn't want this guy as an ex either!
When 19-year-old Nicholas Helman got dumped, he came up with one dangerous plan for revenge - he sent his ex a birthday card.
Thankfully, police were able to intercede in time thanks to a tip. Because the scratch 'n' sniff card was coated with deadly ricin poison!
Luckily the co-worker called the police, who showed up at the ex-girlfriend's apartment complex in hazmat suits, scaring the living bejeezus out of everyone!
But authorities say they were able to collect all the poison and contain the threat - before anyone was hurt!
Nicholas is being charged with attempted murder, aggravated assault, risking a catastrophe, and terroristic threats. All over a breakup.
Ch-ch-check out the video (below) to see the police get their man in custody.
