EL PASO, Texas -- A mad emu gave deputies a Texas-sized hard time. El Paso authorities say the big bird was running loose Tuesday, snarling rush-hour traffic near Interstate 10 and attacking deputies trying to restrain it. Deputies with the El Paso County Sheriff's Office tried to prevent the tall, flightless bird from running into traffic. But when deputies neared the emu, it became aggressive and slashed one deputy's pant leg. The deputy was not seriously injured. The emu died as it was being transported to an animal control shelter. The cause of death was not immediately known.
