Springfield police say a 7-year-old child is hospitalized with life-threatening injuries after being struck by an ambulance.

Police Lieutenant Kenny Winslow said the unidentified child was riding a bicycle about 8:30 p.m. Saturday when the ambulance struck him, throwing him from the bike.

After treatment at the scene, the child was loaded into the ambulance and taken to St. John's Hospital. A hospital spokeswoman said he was still being treated in the emergency room late Saturday.

Winslow said the ambulance was not responding to an emergency when the accident occurred.

He said the cause of the accident is under investigation.
