But as soon as he left one of my friends said 'where did my mobile phone go,'" she said.RECOMMENDED Celebrating the bikini at 70 [PHOTOS] Kellner acted on instinct and chased the man down for about 50 feet before wrestling him to the ground along with one of her friends, who is also a police officer. "I just acted on instinct and didn't think about it so much until after we had pinned him down. When I sat there I looked over at our other two friends who are not police officers and realized that it probably looked pretty funny. But I would have stepped in no matter my outfit," she said.

En stackars hemlös kille som man kan tro försöker göra rätt för sig. Han säljer tidningar istället för att tjuva!! När vi avböjer att köpa hans tidningar passar han på att stjäla min kompis mobiltelefon!! Väldigt skickligt av honom då han smyger ner sina tidningar över mobilen och får sedan med sig den med lätthet!! Osis för denna kille att han råkade sno av två poliser👮🏻👮🏻!! Mitt första ingripande iklädd bikini under mina 11 år som polis!! Ganska kul och trivsamt måste jag säga 😂😂! Se upp för ficktjuvar, håll koll på era värdesaker!!
