More than 20 people were sent to a local hospital Monday morning after an East Haven city bus was rear-ended by a truck on Frontage Road.
According to East Haven officials, some of those injuries were reported to be serious.
Initial investigation reports showed that the bus driven by Alexander Diosa, 37, of Cheshire was stopped at a bus stop to allow passengers to board when a truck driven by Juan Rodriguez, 28, of Allentown, PA, which was carrying cooking grease, slammed into the back of the bus and sent it more than 50 feet down the road.
Pieces of the truck, including an axle, were all over the Interstate 95 service road in East Haven.
Fire officials called the incident "mass casualty" so emergency officials could get enough ambulances to the scene.
Teraja Stevenson said her 18 year-old cousin was sitting in the back of the bus when the truck hit. She said he went flying into something on the bus and fractured his skull.
Officials said 26 people were taken to two different hospitals, including the truck driver, and four or five of the injuries were said to be serious.
Police said one rider was just getting on the bus after putting his bicycle on the front rack of the bus when the truck hit.
Another passenger, a pregnant female, is listed in non-critical condition, but Yale New Haven Hospital officials are keeping her for observation.
Yale New Haven Hospital said three patients arrived at the hospital with full traumas.
East Haven police are investigating the crash.
