(HOWE) – Two people were injured in a multi semi crash over the weekend on the Indiana Toll Road.

Indiana State Police say they were called to the 118 mile marker near Howe at 5:30 PM Sunday for an accident. When they arrived, troopers found three semis and an RV blocking the eastbound lanes. Several people who witnessed the crash and the other involved drivers were assisting one of the semi drivers, 37 year old Parminder Tangar of Wisconsin. They removed him from his rig and were administering first aid.

Troopers applied a tourniquet to his leg to prevent further blood loss. Tangar was flown from the scene to Parkview Regional Medical Center and is in serious condition.

The investigation determined that the crash resulted when the third and rear most semis failed to stop at they approached a traffic back up, due to construction at the 121 mile marker. The rear most semi, Tangar, struck the semi in front of him, driven by 28 year old Mohammed Ghaleb of Idaho. That caused a chain reaction impact with the other vehicles.

Ghaleb was taken to Parkview LaGrange Hospital for medical evaluation.

Assisting at the scene were the Howe Fire Department, the LaGrange County Sheriff's Office and Parkview EMS. The crash is still under investigation.
