From a Walnut Creek Police Department press release:
This morning at approximately 6:11 AM, a Walnut Creek resident noticed a strange man standing in the living room of his residence. The startled resident confronted the man, who immediately fled from the residence toward Ygnacio Valley Road. While checking the area for the described suspect, WCPD officers contacted a subject who was walking on the south curb of Ygnacio Valley Road just a short distance away from where this burglary occurred. Officers detained the subject, who they identified as Alfredo Rene Powell of Hayward. Powell, who is currently on active probation out of Alameda County for a previous offense(s), was identified by the resident as the person he saw running from his residence. The resident believes Powell gained entry into his residence through an unlocked patio door. The resident does not believe anything was stolen from within his residence.
Powell was subsequently arrested for residential burglary and violation of probation. He was transported to the Martinez Detention Facility where he was booked on the aforementioned charges.
