Viescas told the station that he said, "Everyone's trying to sleep here, you know...And then they seen me and they started cussing me out. They were just cussing and trying to act tough."
He says a teen then picked up a 10 to 12 pound rock from his front lawn and hit him in the head with it. Police say once Viescas was on the ground, the teens kicked and punched him before running off. Although badly bruised, he was treated for minor injuries at the hospital and released.

Two of the teens, Christopher Clements of Elk Grove and Matthew Nunley of Roseville, both 18, were booked into the Placer County Jail on $50,000 bail.
The other suspects are 16 and 17 years old.
