Momin Khan has been heartbroken since the moment his 20-year-old son Rahat was shot dead in a suburban street two years ago.

He fled Melbourne's Supreme Court on Wednesday in tears, distraught as his son's killer, Kamil Yucel, 30, was sentenced to five years prison for manslaughter.

With time served and a non-parole period of three years, Yucel could walk free as early as next June.

Outside court, Momin Khan said his family came to Australia when Rahat was seven and his son had taken up cricket and Australian football.
