Six teenagers have been charged over an alleged violent crime spree stretching from the Sunshine Coast to Brisbane, which only ended when they crashed a car in the Clem7 tunnel.

Two 17-year-olds from the Caboolture area, north of Brisbane, are facing more than a dozen charges including armed robbery stemming from four different attacks in a single day.

In one incident it's alleged they robbed a group of teenage boys with a knife while in another they're accused of hitting one man with a glass bottle and another with a wrench.

The other four, including a 15-year-old girl, are accused of varying degrees of involvement in the crimes, from driving the getaway car, allegedly stolen from nearby Morayfield the day before, to taking part in the robberies.
