CHICAGO — The Latest on a roof collapse at a Chicago water reclamation plant (all times local):
Ten people have been seriously injured after an explosion at a Chicago water reclamation plant that authorities say may have been caused by a buildup of methane gas.
Chicago Fire Department officials say two of the 10 had to be rescued from the rubble after the explosion caused a section of the building's roof to collapse around 11 a.m. Thursday.
Firefighters pulled one person out shortly after the collapse. Commissioner Jose Santiago says it took about two hours to rescue the second person, who was "buried and entombed" by fallen debris. Paramedics attended to the man, who suffered a broken jaw and leg, until he could be extricated.
The other people who were injured were taken to area hospitals in serious-to-critical condition.
