Detectives have charged six people following the alleged armed robbery of a Marsden service station this morning.

Around 3.45am, it will be alleged four offenders had their faces covered and were armed with knives when they entered the Chambers Flat Road business and approached the counter.

They then allegedly threatened a staff member before fleeing in a stolen vehicle with a sum of money and cigarettes.

A short time later police located the stolen vehicle parked at the rear of an Eliza Court address.

An 18-year-old Bethania man, 17-year-old Kuraby man and 17-year-old Deagon man have been charged with one count each of armed robbery and unlawful use of a motor vehicle.

The two boys, aged 14 and 15, and a 15-year-old girl will be dealt with under the Youth Justice Act.

No one was physically injured as a result of the robbery.
