A scorned woman allegedly used a popular auto theft prevention device Sunday to take out her frustrations on her apparently cheating boyfriend and his car.

Leina Marie Butler, 38, of Altadena was arrested after police say she used “The Club” steering wheel lock to smash the windows out of her 31-year-old boyfriend’s car and then went after him.

The woman apparently tracked her beaux to a motel in the 2800 block of East Colorado Boulevard Sunday morning where she found him with another woman.

She began attacking his car, but when he came outside, she turned her rage toward him, allegedly striking him in the temple and arm.

He was hospitalized with moderate injuries including a cut to his head.

Butler was booked on suspicion of spousal abuse and is being held in lieu of $50,000 bail.
