A man has run from the scene of a violent robbery, locking the armed man inside before calling police

An armed robber has had the shock of his life after his victim ran from the scene – but not before doing one critical thing that left the thief in big trouble.

An armed robber has had a rude shock after his victim ran from the scene and locked him inside before calling police.

Just after midnight on Sunday, police were called to a service station on Beach Rd at Christies Beach following reports of a robbery.

Police arrived within minutes and found the man locked inside the service station.

Police allege the man was armed with a knife when he entered the premises and demanded cash.

The attendant ran from the scene and locked the man inside before calling police.

The 34-year-old Aldinga Beach man was then arrested and disarmed without incident.

He was refused bail and will appear in the Christies Beach Magistrates Court on Monday.
