A biker received instant karma when he tried to grab a woman by the bum as he sped past – and crashed.

The incident was filmed in the municipality of Ponta Grossa, which is in the Brazilian state of Parana and was captured on CCTV.

The unnamed 35-year-old woman in a grey T-shirt and white cap is seen walking down a cobbled street as the man on the red motorbike approaches. She was apparently on the way home after visiting a local gym.

As the biker comes alongside, he reaches out to grab her bottom, and after releasing the handlebars, the bike tips to one side, and he topples onto the ground, leaving himself scratched and bruised.

It looks as if the bike received some damage as well, and at the end of the video, the biker is seen trying to pick it up.

Police confirmed they started investigating the incident that took place on the morning of 31st January, after the video was made public.

They said that the biker had already driven past once when he realised the woman was alone and decided to drive past again, this time to grab her rear.

As a result of the footage going public, the 32-year-old man was identified and arrested on charges of sexual harassment which can result in a penalty of up to 5 years in prison.

Police also confiscated the motorbike.
