A robbery leads to an assault at a Chico restaurant. The incident started at the Walmart parking lot when a 21-year-old man allegedly stole a cell phone and I-D from a 29-year-old woman on Tuesday. She was accompanied by another woman and a 15-year-old male who reportedly went into the Walmart and purchased an aluminum bat. The trio found the suspect at the In-N-Out Burger parking lot. Police say the teen then chased the unidentified suspect and allegedly struck him multiple times with the baseball bat. Officers arrived and arrested the teen. The 21-year-old suspect was treated for non-life threatening injuries. The DA's Office will look into the allegedly robbery.
