In 2018 John Amaratunga was accused of aiding the fraudulent acquisition of a property worth Rs. 7 Billion from an elderly couple, as well as holding them hostage. Eighty-six year-old Wimalsen Fernando and his wife Shiranie Fernando learnt that their property in Gregory's Road, Colombo was fraudulently acquired by a person named Prasad Deshapriya Vitharana of Kalubowila. When the property was visited by the couple they were held hostage by Amaratunga's guards. When the couple's lawyers attempted to enter the property they met Amaratunga in the property who used abusive language to threaten them and attempted to evict them; but the lawyers forced their way to the couple. The couple was threatened and Vitharana had extorted money from them with death threats. The couple complained to the Cinnamon Gardens police, but they did not see an inquiry for more than five months and no statement was taken from Amaratunga. When the media questioned the police they claimed to be "unaware" of the incident. John Amaratunga accepted that the accused was a friend but denied the allegations that he abused his powers to stop the investigations or that to threatening the lawyers. Instead he claimed he only asked them to leave calling them trespassers.[2] [3]
