Police have captured a would-be dog thief who stabbed two people at a Southern California convenience store in a failed bid to steal their Pekingese.

Lt. Earl Moss says Cathedral City police were called to an AM/PM market Sunday afternoon after a homeless man tried to steal the small dog at knifepoint.

The lieutenant says the dog owner ran out the door with the knife-wielding man chasing him and stabbing him from behind. A second victim tried to intervene and was stabbed in the arm.

Police arrested 58-year-old Jeffery Emerson Gray and booked him for investigation of robbery and assault with a deadly weapon. He's in the Indio jail with bail set at $25,000.
