Authorities say they found a handcuff key and discarded restraints worn by two Northern California jail inmates who escaped custody during a court appearance.

The inmates escaped from a Palo Alto courthouse Monday morning while a deputy was escorting them through a public hallway. Santa Clara County sheriff Sgt. Richard Glennon said the inmates ran through an emergency exit, down stairs and out of the courthouse to a waiting car.

The manhunt continued Monday night.

Santa Clara County sheriff's Sgt. Reggie Cooks says the inmates escaped Monday from a deputy guarding them after they left a courtroom at about 9:30 a.m.

Cooks says it's unclear how they eluded the deputy.

He says the inmates got into a waiting car that was abandoned a few blocks away for a moving van.

The two men had been charged with robbing a Verizon store of $64,000 in merchandise in February and being held with no bail.

The department says they escaped from the Palo Alto courthouse Monday where they were scheduled to attend a hearing in their case.
