Shameless builders were hit with a heavy fine after being caught on camera dumping a mountain of waste onto a children's playing field - weighing more than an elephant. Builders from Triangle Care and Maintenance left corrugated iron, mattresses, cardboard boxes and plastic waste sprawled across the green - weighing more than seven-and-a-half tonnes. Piles of rubbish began falling into a nearby river posing a major threat to both the environment and the local wildlife before Harrow Council ordered the major clean up at Hatch End playing fields in Pinner, north-west London. The rogue company, based in Harrow, north-west London, was sentenced at Willesden Magistrates Court and ordered to pay more than £51,000 for the major dumping caught on camera.
