The Chicago Police Department are investigating the crash at the Cermak-Chinatown Red Line station.  That truck driver was questioned and was taken away in handcuffs after being treated at a hospital.  He tested negative for blood alcohol but refused to take a urinalysis test.  His name has not been released and he has not been charged with anything yet.

Most of those injured were in the bus shelter or the train station stairwell, said fire department spokeswoman Eve Rodriguez.  The truck didn't appear to slow down before the impact, witnesses said.

All twenty-one injured were taken to local hospitals.  Eleven people were in critical condition, four of them are children.  People who work near the station said the intersection the accident occurred at is very dangerous because the traffic lights change quickly.

According to engineers, the only damage to the station was to the stairs that led to the overhead platform.  As of now trains on the Red Line will not stop at the scene until further notice.
