So, this was on twitter:
"#gatwick #drones arrested person wearing hi- viz vest and cycle helmet. Motorist says two drones one 4 ft wide, had flashing lights. Using a pushbike perp. constantly moved, used back streets footway paths and was 'in plain sight' of security forces most of the time says source."
have to agree with our own @sallyhinch: "I shouldn't laugh but it does prove that a) bikes are great for moving around unimpeded and can carry more than you think & b) even in hi vis they really cannot see you"
