A 5-year-old boy accidentally shot his father inside Bass Pro Shops while the man tried on a new holster, police said.

Darren Wayne Lannou, of Canyon, Texas, who has a concealed carry permit from that state, was in the Bricktown sporting goods store Saturday night with his firearm in a holster, according to a police incident report. He took off his holstered gun in a dressing room and placed it on a bench where his son was playing with an iPhone, according to the incident report.

While trying on the new holster, Lannou tried to retrieve his gun but saw that his son had it.

The weapon discharged, causing a graze wound to the boy’s thumb, a through-and-through wound to his father’s right leg and a graze wound to the father’s left leg. Lannou said he grabbed the gun, threw it down, opened the dressing room door and yelled for someone to call 911, according to the report.
