Fresno police say they responded to a gun disturbance between a father and son.
When they arrived they learned that 26-year-old Nanak Phrachanhsay had grabbed a shotgun and loaded a round into it and began pointing it at his dad saying he was going to beat him.
Officers say Phrachanhsay peacefully surrendered and is cooperating with police.
He is now booked in the Fresno County Jail on various weapons-related charges.
