Jacksonville, Florida, USA, A Kenyan man man faces two sexual battery charges following his arrest in a local nursing home. According to the Jacksonville Sheriff's Office, it happened just after 3:30 Sunday 13th September, 2009 morning at the Regents Park nursing home on the Southside. A witness told police she heard something from one of the rooms, and when she went in she saw Anthony Mbugua Njoroge engaged in a sexual activity with a woman in the room. The woman is disabled. The witness told police she reached for her cell phone, but Njoroge tried to stop her. She was able to make a call anyway and someone else came into the room. That witness told police she saw Njoroge cleaning up. The witness says Njoroge then left the room and threw something in the disposal room. Police came and investigated, then arrested Njoroge. Njoroge, 35, faces charges of sexual battery (victim mentally impaired) and sexual battery (victim physically helpless.) "When something like this happens, especially to someone of a certain age, it's disgusting," said John Harrell, spokesperson for DCF. The Department of Children and Families is working alongside JSO on the investigation. Harrell says DCF has investigated eight allegations of abuse at Regents Park in the past year, though none have been verified. "Of those eight reports, four showed no findings, but four had some findings, including inadequate supervision [of patients]. That happened a couple of times," Harrell said. Regents Park Spokesperson Tom Groesbeck confirmed Njoroge was employed at the nursing home, and that the care facility is cooperating with law enforcement on the investigation. A former employee of Regents Park told First Coast News that Njoroge has worked at Regents Park as a nursing assistant since at least 2005. First Coast News has learned that Njoroge also worked at another Southside nursing home. A spokesperson for Life Care Center says Njoroge was employed at the nursing home up until his arrest Sunday. The spokesperson went on to say that resident safety is Life Care Center's highest priority, and that there have been no allegations of this nature at their facility. Authorities say the elderly victim from Regents Park is doing as well as can be expected. DCF is now looking into whether the attack is an isolated incident. "Obviously there are a number of vulnerable adults there. They need to be safe. They need to be in a safe environment. I'm sure there are a lot of families feeling a lot of concern right now," Harrell said. Police are withholding any further information due to the nature of the crime and the investigation. Njoroge remains in jail on a $500,000 bond. Aside from this arrest, he has no criminal record in Duval County.
