Part of an exterior wall collapsed at a west suburban state office building Sunday.

Officials say a pileup of snow and ice caused the damage to the wall at the Lombard State Unemployment Office.

The portion of the wall that fell also severed a natural gas line, causing a leak.

Emergency crews blocked access to the area until Nicor crews were able to shut off the gas line.

Nobody was in the building at the time of the wall collapse.

There were no injuries.
