Patrons at a Cheyenne Starbucks got more than a shot of espresso Monday morning, when a gun inside a girl's purse fired inadvertently.

Though several people were reported to being inside the coffee shop at the time, there were no injuries.  The single bullet, which fired around 7 a.m. Monday morning, reportedly went through a chair and into a wall, narrowly avoiding many customers.

Police officers were at the Starbucks at the time and say the girl, who is under 18 and has not been identified, was cited for possession of a firearm by a juvenile which carries a $750 bond.  The juvenile has since been released to the care of her parents.

The gun had been given to the girl by her father who encouraged her to carry the firearm for protection.  Police reports indicate that she had received no formal firearm training.
