CHICAGO (CBS)–A six-month-old was rushed to the hospital on Monday after a minivan crashed into three vehicles and a CTA bus and led Chicago police on a chase on the Southwest Side.

The baby is expected to recover, police said.

The situation started around 1:15 p.m. near the Leighton Criminal Court House on 26th and California when a Chrysler Town & Country minivan crashed into a Nissan Altima, police said.

The six-month-old, a passenger in the Nissan, was taken to St. Anthony’s hospital in good condition.

An officer saw the minivan speeding on the 1400 block of South Kedzie and tried to pull it over, but the driver continued on, according to police. The minivan continued driving and struck a Subaru driving west on Douglas, police said.

“Thank god there wasn’t time for them to get out of school,” said Luleeliza Coleman, a safe passage worker who works nearby. “Oh my God, it would have been–it would have been so sad.”

The Subaru spun out and struck a Lexus, while the minivan crashed into a CTA bus, authorities said.

The driver of the Lexus was taken to Stroger Hospital in stable condition. The driver of the Subaru and a passenger refused medical attention.

The CTA bus driver declined medical treatment. Police said the bus was empty when it was hit.

The driver of the van was hospitalized in good condition and is in police custody.

Police are still investigating whether a high rate of speed by police officers may have contributed to the crashes.
