Exeter police say, on Feb. 1, the teen had walked up to the group, pointed a gun at them and tried to fire it. The gun malfunctioned, and the suspect ran away when he couldn't fix it.
Officials did not say how many people were outside of the home.
Saturday, after a month-long investigation, Exeter police detectives arrested the teen and booked him into the Tulare County Juvenile Detention Facility.
