Charge delays queried.
A judge at Cardiff Crown Court yesterday locked up Ben Emmott, 18, for two years after he pleaded guilty to robbery, affray, having a weapon and criminal damage.
The court had heard Emmott, of Knightswell Road, Caerau, had committed the affray in the middle of September, having already been arrested for the robbery in July.
He was not charged with robbery until September 23.
"Charging him earlier with the first offence may have avoided the second," said his barrister Lucy Crowther.
Ms Crowther said both incidents had been unsophisticated and unplanned and Emmott had been drinking each time.
