Lawyers for convicted murderer Took Leng How say some 34,000 people have signed a clemency petition against his death sentence.
The petition was submitted to President SR Nathan on Thursday, and a decision is expected over the next few months.
Took's parents took to the streets to ask Singaporeans for support for a plea for their son to be spared the death penalty.
The vegetable packer, a Malaysian, was sentenced to death in August last year for the murder of 8-year-old Huang Na in October 2004.
Since the verdict for the appeal against the death sentence in January was split, some of the petitioners felt the 22-year-old deserved a second chance.
Justice Kan Ting Chiu delivered the dissenting judgment that Took should be convicted for voluntarily causing hurt rather than murder. - CNA/ir
