A dramatic video has emerged from the United States of a man performing a citizen's arrest on a motorist he suspected of driving under the influence. <br /><br />The footage, captured in Houston, Texas on July 22, shows the motorist driving extremely erratically with his front bumper hanging loose after an earlier crash. <br /><br />The filmer's car can be seen tailing the vehicle as it veers wildly back and forth across the road. <br /><br />The driver then pulls up in a car park, allowing the filmer and his family members to assist with getting the driver out of the car. <br /><br />Police then arrive promptly to lead the suspect away. <br /><br />"Many people have criticised how I acted, telling me that I shouldn't have got involved, that the guy could have ran me over and kill me. But at that point I only thought of doing something before someone got hurt," the filmer wrote online. <br /><br />"I thought of two really good friends of mine that are now dead, one because he drove while really drunk and he crashed and died and the other one a few years later, died because he got hit by a drunk driver," he added.
