Authorities first received an allegation of child abuse on Thursday after staff at a medical center reported that they treated a baby who had serious bodily injuries.
"A mother had brought her 8-month-old son in with unexplained injuries," said Sgt. Lisa McConnell of the Ventura County Sheriff's Department.
The investigation led officers to Washington Family Child Care, a licensed daycare facility on the 1100 block of Lee Ann Circle. Tyreece Washington was arrested Monday for felony child abuse.
Police say Washington's mother runs Washington Family Child Care out of her home, and the 8-month-old was an infant she was looking after. Neighbors were shocked to hear the news about the arrest.
"All I do know for a fact is that he's a good, well-mannered young man," said neighbor Mark Meijer.
Washington is being held at the Larry Smith Correctional Facility on $42,000 bail.
The Department of Social Services is investigating. Details about the infant's injuries were not yet known, but officials said he is expected to make a full recovery.
