A 2-month-old girl was taken to Toledo Hospital Tuesday night with injuries to her head, police said.
Toledo firefighters responded to a house in the 400 block of Southgate Circle Drive about 11:30 p.m. on a report of an unresponsive child.
The infant, whose name was not released, was breathing when crews arrived, but had suffered head trauma.
"The child has some serious, unexplained injuries," said Toledo police Sgt. Tim Noble.
No charges have been filed in the case. The investigation continues.
