It doesn't appear to be a calculated heist a la Kim Kardashian's infamous gunpoint jewelry robbery in Paris: a man approached Styles while on a night out, pulled out a knife and demanded cash, which Styles handed over.
"He actually played it pretty cool, quickly giving the assailant cash, keeping himself and the guy calm and getting the situation over with," a source reports.
It was a tough weekend for Styles. In another tragedy, randomly occurring the next day, Styles' ex Love Island star Caroline Flack passed away of suicide this past Saturday. The pair met on The X-Factor and dated in 2011 when Harry was 17 and Flack was 31.
