Officers went to the 1400 block of Southdown Road at about 11:05 a.m. on a report that a woman had been confronted by an unknown man inside her home, according to the Hillsborough Police Department.
The man was reportedly carrying property belonging to the woman, which he dropped when he saw her. One of the victim's dogs then chased the suspect out of the house and off the property.
Police searched the area but did not find him.
The suspect was described as a clean-shaven Hispanic man with a round face. He is between 35 and 40 years old and has dark hair combed into a wave in the front. He was seen wearing a gray knit crewneck sweater.
Anyone with information about the suspect or the attempted burglary is asked to contact Hillsborough police Inspector Nick Chinca at (650) 375-7456.
