A northwest suburban man locked up for choking a woman used his one call while in custody to phone her and threaten to kill her, authorities say.

Janusz Owca, 32, of the 9400 block of Bay Colony in Maine Township, is being held on $350,000 bail on charges of aggravated domestic battery and felony intimidation, according to the Cook County sheriff’s office. He already was on probation for a domestic violence conviction last month.
