UK Woman Convicted in Acid Attack A young British woman has been convicted of disguising herself in a veil and throwing acid on her friend's face following an argument. Police said that Mary Konye, 21, was "obsessively jealous" of her friend Naomi Oni's "good looks" and had spent several months hatching a plan for the attack. After following Oni home from work, Konye - disguised in a niqab - threw sulphuric acid on Oni in the early hours of Dec. 30, 2012. The attack left 21-year-old Oni with disfiguring burns on her face, hand and thigh. Konye had denied the charge of throwing acid with intent to "burn, maim, disfigure, disable or do grievous bodily harm." Judge David Radford warned Konye will likely face "substantial" time in jail when she is sentenced on March 7.
