An officer contacted the suspect earlier in the morning before the start of revenue as a result of a welfare check. During that welfare check, the suspect had several suspicious items on him, such as a dealer license plate and a bag full of car keys. At the time, the officer was unable to confirm if the items had been stolen. The suspect was identified and released, but the officer retained the property. A few hours later, the officer was able to confirm that the dealer plate and keys had been stolen in a burglary from Toyota of Walnut Creek. The officer contacted Walnut Creek PD (WCPD) and confirmed they were searching for a suspect in that burglary. The officer located the same suspect from his earlier contact who was still at the station. The suspect was detained and WCPD arrived a short time later to take custody of the suspect and place him under arrest.
