Questions have been raised after a video showed Thai authorities hurling a monitor lizard over a wall after it wandered onto a busy motorway.<br /><br />The reptile was seen on the highway in the Din Daneg area of Bangkok, Thailand, last Friday.<br /><br />Rescue workers arrived and snared the animal with a lasso before lifting it in the air and throwing it unceremoniously over the edge of the raised road into bushes. <br /><br />The treatment of the animal in the video appears overly rough but authorities said the animal was completely unharmed and had been saved from certain death. <br /><br />Volunteer animal handler Khun Nakorn said: ''There were a lot of cars and the lizard could have caused an accident. It had to be dealt with quickly. We had to get it off the road. It wasn't injured.''
