A Texas man is in custody in Minnesota after allegedly firing a gun at another motorist.

The Watonwan County Sheriff's Office says authorities responded to a reported road rage incident on a road south of St. James on Thursday evening. The caller said a man in another vehicle pointed a gun out the window and fired a single shot in his direction.

It wasn't immediately clear what sparked the alleged incident.

Authorities later located the suspect, his vehicle and the gun at a St. James home. They arrested a 28-year-old man from El Paso, Texas. Formal charges were pending.
