which Chiara Sangiorgio, of Amnesty International called ‘cruel and inhumane’. Nagaenthran Dharmalingam In April 2009, Nagen, a 23-year-old Malaysian man, with intellectual disability, was arrested at the Woodlands Checkpoint entering Singapore with 43g of heroin strapped to his thigh. He was sentenced to death in November 2010. Although considered to have intellectual disability, the court held that it was not severe enough so that he must have known what he was doing at the time of the offence and that no other evidence of his disability was required. Nagaenthran was executed on 27 April 2022, despite pleas against this from many nations around the world. Prabagaran Srivijayan 25-year-old Malaysian man was arrested in April 2012 when 22g of heroin was found in the car he was driving, which he had borrowed from a friend. There was evidence of an unfair trial and a failure by the authorities to investigate evidence which could exonerate him. His lawyers were not permitted to visit him in Changi prison. And although he co operated with the investigating authorities they did not provide him with a certi cate of assistance which would have allowed for his death sentence to be commuted to a life sentence. The DPP began an appeal in the Malaysian courts in January 2017, however, Praba was was executed in July 2017, while an appeal was still pending.
