Three-time Olympic hammer throw champion Anita Wlodarczyk from Poland caught a car thief and injured herself. The man tried to steal her car.

“I single-handedly arrested the thief and handed him over to the police. Unfortunately, I paid for it with a muscle injury,” the 36-year-old wrote on Instagram. She will therefore have an operation on Monday. The exact nature of the injury was not clear from the post.

Wlodarczyk, who last year in Tokyo was the first athlete to win Olympic gold three times in a row in one discipline, was also considering whether she would later switch from the hammer throw ring to another. “After my career, I think I’ll fight like our champion Joanna Jedrzejczyk in MMA or UFC because the perpetrator was injured,” wrote the 36-year-old, not entirely serious about a possible career in a full-contact martial art.
