The prosecution has sought a sentence of at least five years' jail for a man who went on the Dark Web to hire a hitman to murder the boyfriend of his former lover through a staged car accident.

On Monday, Deputy Public Prosecutor (DPP) Kumaresan Gohulabalan told the court that risk management executive Allen Vincent Hui Kim Seng, 47, was unable to move on from his former girlfriend,  Ng Woan Man, 30, remaining "obsessed" with her and stalking her "incessantly".
