TENANTS HARBOR, Maine — Police are investigating an incident in which a baby suffered a head injury but stressed that it does not appear to be suspicious.

The Knox County Sheriff’s Office received a report at 5:45 p.m. Saturday from the Maine Department of Health and Human Services that a child less than a year old had been taken to Pen Bay Medical Center in Rockport with a traumatic head injury.

The hospital was mandated to report the injury to DHHS, which then referred the matter to the sheriff’s office.

Deputies stood by at the child’s residence until detectives from the Maine State Police Major Crimes Unit arrived.

Because of the age of the child and the reported injuries, state police protocol dictates that an investigation is to be conducted by that agency.

The child was listed in satisfactory condition as of 11:30 a.m. Sunday.

“At this time there is no indication of any suspicion. The parents are cooperative and assisting with the investigation,” said Knox County Chief Deputy Tim Carroll.
