Two teenagers have admitted being involved in a knifepoint robbery at a Cumbrian post office.

Reece Kirk, 19, and a 17-year-old male who can't be identified because of his age, appeared at Carlisle Crown Court today.

Both admitted robbing a staff member at Ravenglass Post Office of cash on January 11.

The court heard a "drug debt" prompted Kirk to carry out the robbery at about 10.20am that day.

He accepted possessing a knife during what he claimed had been a "joint enterprise".

Judge Peter Davies adjourned the case.

Kirk, of Murrayfield Terrace, Ravenglass, was remanded in custody and the youth was granted conditional bail.

Both are due to be sentenced at the crown court on April 21.
