A Liberty mother called police after coming home about 3:30 p.m. Thursday and discovering her 13-year old son making an explosive device.
Police and fire officials found a white PVC tube with a copper cap filled with fireworks in the house at 2315 E. H Highway near the city’s eastern limits, said Liberty Police Capt. Andy Hedrick.
The house was evacuated and the Kansas City bomb and arson squad was called in to do a controlled detonation. There were no injuries.
The teenager was taken into custody and the case is under investigation.
