MAJOR concerns have been raised about attacks on 5G masts in Bradford, with those responsible urged to stop before someone is seriously injured - or worse. Three, the telecommunications and internet service provider, says its engineers have faced abuse simply for doing their job, with one mast coming under attack four times. The Telegraph & Argus has reported on a number of deliberate attacks on masts in recent months. In November, dramatic pictures emerged of a mast in a residential area of Bierley engulfed in flames. When such attacks have happened, police have driven home the point that any deliberate ignition "presents a significant risk".
