A Meriden father accidentally shot his 17-year-old son on Friday afternoon while allegedly teaching the boy about firearms, police said.

The teen was shot once near his shoulder with a 9mm handgun around 3:05 p.m. on Forest Avenue, according to the Meriden Police Department.

The boy’s father allegedly accidentally shot him while he “had been showing him the weapon,” police said.

“The father was planning on getting his son acclimated with firearms in order to begin firearms training at a local gun range in the near future,” the police department said in a statement.

The boy was taken to the hospital in an ambulance and then transferred to a trauma center by Life Star, police said.

Police were still at the scene of the shooting Friday evening and the investigation was ongoing. No one else was injured, police said.
