By John Hall PUBLISHED: 11:46 EST, 28 February 2014 | UPDATED: 13:11 EST, 28 February 2014 A coroner has recommended that dangerous lakes are dyed black or ringed with stinging nettles to discourage swimmers, after hearing how two people drowned at a beauty spot on the same day. Ryan Pettengell, 41, and Umar Balogun, 16, drowned in separate incidents at Bawsey Pits in Norfolk on July 16 last year after going swimming on a hot summer's day. Swimming is banned in the waters because of dangerous, near-invisible weeds growing below the surface but warning signs are often ignored.
