BATON ROUGE - A now-former Baton Rouge Police officer has been charged with third-degree rape in a 2022 attack on a woman he visited in Zachary.

Demichael Robertson, 30, was initially arrested in early August 2023 on sexual battery charges in a case reported to have involved a 4-year-old girl. Court records do not show that he has been formally charged in that case.

After that arrest, a woman contacted Zachary Police to report the December 2022 rape. She told investigators that she invited him to her home, where he forced her to have sex with him, according to an arrest warrant.

She did not report the crime to law enforcement at the time because he was a police officer, she said. She did seek medical treatment at a hospital, where she was examined by a nurse specially trained in handling sexual assault cases.

She provided the nurse with a used condom from the attack and a written statement about the crime. The nurse also completed a sexual assault evidence collection kit as part of the examination, the warrant said.

The woman told Zachary investigators that after she saw the news of Robertson's first arrest, she decided to report the crime to law enforcement, the warrant said.

Robertson was arrested in the rape on Aug. 22, 2023. He had been placed on administrative leave after the first arrest, police said, and was fired in December. He worked for BRPD for eight years.

Robertson was charged in the rape case Friday.
