Esther Afrifa bought a litre of sulphuric acid from a website to prepare for attack. Threw it on Kelvin Pogo at 3.30am while he was sleeping, leaving him wounded. She then attacked him again while he was lying on a sofa already badly injured. He said: 'She used to be my world and she did this to me - I can't understand it' A jealous woman doused her sleeping boyfriend with acid and then attacked him a second time while he was lying wounded after mistakenly believing he was having an affair. Esther Afrifa, 28, who has been jailed for 14 years, bought a litre of sulphuric acid from the Internet and left it by her bedside ready to attack 29-year-old Kelvin Pogo at their home in Wembley, north London. After the first attack, Afrifa went to extraordinary lengths to stop Mr Pogo getting medical treatment, leaving him with lifechanging injuries that have left him plagued by suicidal thoughts.
