WICHITA (AP) – Wichita police say a 15-year-old has been arrested after threatening to cut off his older brother’s genitals during an argument over a video game.

The Wichita Eagle reports the incident happened at 1:20 a.m. Sunday. Police say the 15-year-old pulled a knife, held it to his 20-year-old brother’s throat and made the threat.

The brother wasn’t hurt, and police don’t know which video game prompted the fight.

Police spokesman Sergeant Bart Brunscheen says the 15-year-old is listed as an active runaway in a separate case. The boy was arrested on a charge of aggravated assault and criminal threats.
