Lakhvinder Cheema was murdered on 27 January 2009 in Southall, West London, by his former lover, Lakhvir Kaur Singh through the use of poison derived from the Aconitum ferox plant, which contains the highly toxic alkaloid pseudaconitine. Singh became known as "The Curry Killer" due to the food to which the poison was added. The case is of note due to the cruel method of killing and the degree of premeditation, with Singh travelling to India to procure bikh poison, prepared from Aconitum ferox. Singh received a life sentence with a 23-year minimum term.
