The toddler was taken to a hospital Sept. 13, suffering from a high fever, badly abused and bleeding from the vagina.
Police announced Wednesday they had arrested the five people -- three men and two women -- who took her to the hospital.
Initial reports suggested the girl had been raped because she was bleeding from her vagina, but police Thursday denied those reports, Gulf News said.
"The hospital immediately called the police who requested a diagnosis of the girl's condition. The report said that she had not been raped or sexually assaulted. However, it said that she suffered from lack of hygiene and [was victim to] physical aggression that required an investigation," said police spokesman Nawaf Bin Nasser al-Bouq.
The group of people who took the toddler to the hospital said they weren't her relatives and that her parents left the girl in their care when they left Saudi Arabia.
