The handsome looking BMW had its windscreen, back and side windows cracked after this shocking incident in Cardiff.
The violent woman must have used a metal tent peg to hit the windows of the BMW which had its number plate ripped off. The footage shows her using both arms to hurl the heavy rock through the passenger window.
The footage was caught by Ben Taylor, 21, who said the woman spent 10 minutes destroying the car in Whitchurch.
He said: ‘She was smashing up the car for about 10 minutes. She kept smashing the windows with what I think was a tent peg.
‘She was there for so long the police had turned up seconds after she had run away.’
The pictures were posted on social media, who then came to a conclusion that she had been getting revenge on a ‘cheating boyfriend’, but neither were named.
South Wales Police confirmed they were called to the scene but no arrests were made.
