Police say Jason Landes-Caballero, 21, of Pleasanton, came into the pub with friends but then became separated from them. At some point in the evening, he began acting strangely, pacing back and forth. Shortly before 1 a.m., he took out a silver handgun and fired over patrons' heads, according to a statement from Pleasanton police Sgt. Maria Munaye.
Several of the bullets hit the restaurant's ceiling, but one struck a patron in the buttocks; that man did not realize he had been hit until friends saw that he was bleeding. The victim was taken to St. Eden Medical Center with superficial wounds and released after a couple of hours.
Waiters chased Landes-Caballero through the streets but could not catch him. They turned to social media to inquire about the customer then passed along the information to the police, resulting in an arrest, according to Mary Kennard, owner of Redcoats British Pub & Restaurant at 336 St. Mary St. in Pleasanton.
"This was a troubled young man," Kennard said. "I want to give credit to the staff. It's shocking, but we're happy that it wasn't more serious."
Landes-Caballero was arrested Sunday afternoon on suspicion of assault with a deadly weapon and negligent discharge of a firearm. He was also charged with possession of a controlled substance after methamphetamine was found on him.
Kennard described her pub as a family establishment that turns into a fun bar in the evening.
"Nowhere are we immune from a troubled young man with a gun," she said. "I guess it's just the price we pay for living in a free society."
