A dramatic video has emerged of a group of young cyclists circling a biker and allegedly trying to steal his keys and helmet-mounted camera in London, UK.<br /><br />The footage, shot on Saturday near Westminster Bridge, shows the young men riding next to the motorcyclist until he stops.<br /><br />Once they come at a halt, one of the cyclists appears to try and grab the biker's helmet camera while another one can be seen putting his hand over the motorbike keys. <br /><br />"[They] tried to kick my sports bike as I was going to overtake the grey Prius car in front of me," the filmer wrote online. <br /><br />"It was a very tense situation, I'm pretty sure both them and I were waiting for the other to make the first move to then attack the other," he added. <br /><br />The biker later explained that boys from the group tried to get in touch with him explaining that this attitude was unusual.<br /><br />"Olders from the group message me and tell me that these lads are trouble makers and don't represent their group," he said.
