Update: Officer released from hospital, investigation continues. Last night at around 7 o'clock Hayward Police got a call from someone saying they were fighting with their roommate and that the roommate had their car keys and wouldn't give them back. The caller also said their roommate could be under the influence of an illegal drug. Our officers responded and tried to talk with the suspect, but he was uncooperative and would not follow any directions. When officers tried to detain him, he aggressively pulled away. A taser was deployed but the device had no effect. Suddenly, the suspect grabbed a large metal bar off the ground and lunged at one of our officers striking her in the arm with significant force. The officer then fired her service weapon striking the attacking suspect. Both the suspect and our officer were transported to nearby hospitals. Our officer was treated for her injuries and released. The suspect underwent surgery and is in critical, but stable condition. At this point in the investigation, the suspect's identity has not been confirmed as he is still receiving medical treatment. The involved officer is a 15-year veteran of the Hayward Police Department. We again thank our community for your patience and understanding, while we continue to investigate this incident. As we acquire more details and are able to confirm additional facts, we will provide everyone with more information. Per Alameda County protocol, the Alameda County District Attorney’s office is also conducting a parallel investigation.
