Cook County Sheriff Tom Dart says the last four hostages have been released unharmed to end a standoff with two armed men in a southern Chicago suburb.

Dart says the two adults and two children still being held were freed Wednesday morning without a shot being fired. He says two suspects have been arrested.

The standoff began about 21 hours earlier when police in the small city responded to a neighbor's report of a possible burglary at the home.
