Investigators say an 11-year-old northern Indiana boy shot and wounded his state-trooper father because he was upset that his parents took away his video games.

The South Bend Tribune and WSBT-TV report that investigators say in court records that the boy used his father’s service weapon to shoot him once in the buttocks last month. They say the boy got the gun from the trooper’s locked police vehicle outside their home in Granger, near South Bend.

St. Joseph County prosecutors have filed a petition alleging delinquency for attempted murder, which is the juvenile equivalent of a criminal charge. The trooper, who was off-duty when he was shot, was hospitalized afterward and his condition has improved since then. The Associated Press isn’t naming him to avoid identifying his son.

The boy is due back in court April 10.
