An off-duty Chicago Police officer was stabbed while driving Friday morning in the South Shore neighborhood, causing her vehicle to hit a school bus.

The 47-year-old woman suffered multiple stab wounds while driving at 8:14 a.m. near 76th and Stony Island Avenue, according to  Chicago Fire Department spokesman Larry Merritt and Chicago Police.

Police called the attack a “domestic incident” and said the woman was taken to Northwestern Memorial Hospital in serious condition with a head injury.

Her condition has been stabilized, Merritt said.

As a result of the stabbing, the vehicle crashed into a school bus, Merritt said. A 12-year-old boy who was on the bus was taken to Jackson Park Hospital to be treated for a headache.

No suspect was in custody Friday morning.
