A Chicago assault suspect tried to go from villain to hero to impress a female co-worker, but wound up in jail after the damsel in distress realized her attacker and “rescuer” were one and the same.

Donquila Butler, 29, a hospital security guard, was ignored each of the numerous times he waved to another hospital employee who worked in the records department. By Sunday, he was fed up, the Chicago Sun-Times reported.

Donning a ski mask and hood, Butler went to the victim’s work area, grabbed her by the throat and said, “Shut the f—- up before I kill you right here,” police told the Sun-Times. When other hospital employees saw the incident, he reportedly ran off only to return minutes later without the mask and hood to “rescue” the woman.

Butler’s alleged plot was thwarted after the victim recognized him, the Sun-Times reported. He was arrested Tuesday and charged with felony unlawful restraint.
