SAN JOSE – Authorities are investigating the armed robbery of two off-duty Santa Clara County Sheriff’s Office corrections deputies early Saturday morning.

The robbery occurred on the 1500 block of Almaden Expressway, near West Alma Avenue, about 2:30 a.m., according to San Jose police Sgt. Enrique Garcia.

Garcia said two men – one armed with a handgun and the other with a knife – robbed the deputies and one other victim of personal property, which did not include any weapons.

The victim who was not a deputy was also assaulted and treated for non-life-threatening injuries.

“Based on the preliminary investigation, there is no indication the suspects knew two of the victims were law enforcement officers,” Garcia said.

The sheriff’s office said it was aware of an “unfortunate incident” involving two of its off-duty employees.

“All proper notifications were (made) after the incident occurred,” the sheriff’s office said in a statement Tuesday night.

Both suspects were described as Latino with short black hair and facial hair, according to Garcia.

The suspect armed with the knife was about 25 years old and 5 feet 7 inches tall with a medium build. He was last seen wearing a gray hooded sweatshirt and dark-colored pants.

The suspect armed with the handgun was about 5 feet 10 inches tall with a heavy build.

The armed robbery remains under investigation and police are asking anyone with information to contact the robbery unit at 408-277-4166.
