Carlisle man was sentenced to 30 months in prison at Carlisle Crown Court.
Michael Dean-Norman, 20, of Yewdale Road, Carlisle was jailed to 18 months for robbery and a further 12 months following the revoking of his suspended sentence at Carlisle Crown Court on Thursday September 1.
Detective Constable Gabrielle Nicholson said: “Dean-Norman made serious threats to the victim that he would cause him harm if he did not hand over the money.
“These offences can be terrifying for the victim and can have a last affect.
“We take robbery offences extremely seriously and such threatening behaviour will not be tolerated.”
On the evening of August 3 this year Dean-Norman approached the victim at a cash point on Hutton Way, Carlisle.
Dean-Norman shouted at the victim and asked how much money he had taken out before demanding the money and making threats on what he would do if he did not give the money and said he would take the victim bike instead.
On the bike Dean-Norman has made further requests for the money which the victim ignored and walked away.
The victim’s bike was returned, and Dean-Norman was arrested shortly after the incident by officers.
