42 year old Mairi Kerin, was about to pay for some items at the LOCO Convenience Store in Telford, Shropshire England. An unnamed 18 year old wearing a hoodie and ski mask came in and announced he was robbing the place. Not on her watch. Mairi grabbed his arm and delivered a crushing kick to his shin and then as he turned to run she got a shot in on the back of his head. She nonchalantly walked back to the register to pay for her items. The teen needed medical attention and when he went local doctors had been told to be on the lookout for someone with these injuries. The led to his arrest and 2 others who as a gang of 3 have been robbing convenience stores since the Summer of 2023.
Mairi is an award winning Brazilian jiu-jitsu and karate black belt. After watching the security video where she appears to kind of swagger back to the counter she laughed and said it was actually because her feet hurt from wearing a new pair of high heels!
