When confronted, the intruder fled from the home, heading toward Ygnacio Valley Road.
Police checked the area and found the suspect walking on Ygnacio Valley Road, not far from where the incident had been reported.

Powell is on probation in Alameda County, and was identified by the Homestead Avenue resident as the intruder, police said. The resident told police he does not believe anything was stolen from the home.
Powell was arrested on suspicion of residential burglary and violation of probation, and was booked into the Martinez Detention Facility.
