Three people in this video are caught in the act.
A would-be thief had his plot foiled when he opened the door to a car he was targeted and found the owner having sex inside.
The surprised owner jumped out with his trousers still round his ankles then gave chase in a quiet part of Wu’an City, China.
He was unable to catch the man so asked for the CCTV footage so that he could give it to local police saying the thief ‘only took three seconds to force open the door.’
He added: ‘Had I not been there, my car would definitely have been stolen.
He declined to answer what he was doing inside the car when he was caught or explain why the car was rocking before the thief opened the door.
