Ten minutes later, police allege a second robbery was committed, this time on South Road in St Mary's.

There it's alleged the teens jumped the counter and punched one of the attendants.

Less than an hour later, police were called to a third hold up, this time on Fiveash Drive at Pasadena.

The boys allegedly used a knife to threaten staff before, again, punching an attendant.

The spree came to an end in a carpark, where police tracked down the trio and their allegedly stolen getaway car just before 2am this morning.

Fortunately the injuries to the two service station operators were minor, however one did require medical treatment.

The arrested trio faced court today, charged with multiple counts of aggravated robbery.
