A Launceston man has been jailed for an aggravated robbery where he choked the victim.
Ricky John Izard, 22, was found guilty by a jury of punching the man to the ground from behind then taking his wallet in Lawrence Street in Launceston in 2012.
While on the ground man was punched twice more causing the back of his head to hit the pavement.
Izard and an associate demanded the man's pin number threatening they knew he lived and would ``f**k him up'' if the number was incorrect.
``The initial forceful blow was from behind and the violence continued while he was defenceless and on the ground,'' Justice Robert Pearce said.
Izard was sentenced to 15 months prison with the final 28 weeks suspended.
