Santa Rosa police took a 29-year-old Rohnert Park man into custody Saturday on suspicion of vandalism and battery on an officer after witnesses said the man became violent at a Starbucks coffee shop.

Employees of the shop, at Stony Point and Bellevue Ranch roads, said Jesse Stevens arrived at the store very early and began acting strangely.

Around 7:45 a.m., he locked himself in the bathroom and began pounding on the walls and door, employees told police. At one point, he tried to pull an employee in with him, they said.

Employees and customers evacuated the business and called police.

Stevens then began throwing furniture at the front windows and emptied the cash register onto the floor, Sgt. Dave Linscomb said.

When an officer arrived, Stevens broke out the front door glass, Linscomb said, and charged the officer. An "electronic control device" had no effect.

Stevens swung a piece of patio furniture at the officer, Linscomb said. The officer's name wasn't released.

Other officers arrived and helped take Stevens into custody. He was treated at the scene by paramedics and later at a hospital for what police said were self-inflicted injuries to his head and arms.

The officer was treated for minor injuries and released.
