Upon reportedly finding stolen jewelry and small electronic items on the pair, police arrested both for burglary shortly before noon, Sgt. Matthew Ortega said.
Luis Cadena, 18, of East Palo Alto, and a 17-year-old male companion were booked on suspicion of residential burglary. They'd reportedly climbed through an unlocked dining room window.
Police spokeswoman Nicole Acker said the investigators believe the pair also attempted to burglarize another house on the same day.
A resident in the 2000 block of Menalto Avenue came home around 5 p.m. to find window screens removed from the house, but the would-be thieves failed to get inside, Ms. Acker said.
No word yet on whether the two men may be linked to the other burglaries plaguing the Willows during the past six months. The city hosted a community meeting last week to discuss the incidents.
Police ask anyone with information about the burglary to call 330-6300.
