Police arrested a man they say abused a five and a half month old boy in St. Petersburg.
Michael Hylton, 32, was charged with child abuse-aggravated battery causing great bodily harm.
The baby suffered severe head injuries and other serious internal injuries consistent with physical abuse.
Hylton was reportedly the only one caring for the child at the time he was injured, and police say he could not provide any explanation for the injuries.
The infant is currently being treated for his injuries.
