Sri Lanka’s President, Maithripala Sirisena caused an outrage after pardoning the killer of a Swedish teenager who was murdered in 2005.
The victim’s sister, Caroline Jonsson, said the killer had shown no remorse.
Jude Jayamaha, who was on death-row for the murder is from a wealthy, high-profile family.
Last month Sirisena announced he was considering a request to grant Jayamaha a pardon, saying he had behaved well in prison and had been jailed aged 19 “over an incident of impatience”.
Sirisena will not be standing in the presidential election next scheduled for next Saturday, after he failed to get support from his own party to contest polls.
Sri Lankans took to social media to criticise his move.
Victim Yvonne Jonsson, a dual national whose mother was Sri Lankan, was beaten to death in the stairwell of the apartment block where her family was living in the capital Colombo in 2005 after an earlier argument with Jayamaha.
During the trial, the court heard that her skull had been fractured into 64 pieces.
Jayamaha was initially given 12 years in prison. His subsequent appeal against his jail term was rejected and he was sentenced to death instead, a sentence upheld by the Supreme Court in 2014.
