A lockdown was in effect for a time Wednesday night at a strip mall in south suburban Matteson after a reported robbery at a Sprint store.

The two workers inside the store reportedly ran into a back room and called the police.

Shoppers in nearby stores were temporarily locked down while police searched for the gunman.

The gunman was not found and the lockdown was lifted.
