Police in central England have warned locals to beware of a large, aggressive bird which has gone on the run saying it posed a “very real threat to the public”. The 6ft (1.83m) rhea, a tall flightless bird native to South America, went missing from a private collection in Carlton-in-Lindrick, Nottinghamshire, on Tuesday and has not been seen since. “We are warning local people and particularly those with small children to be on their guard and not to approach the bird, which poses a very real threat to the public due to its size, aggressive nature and the unfamiliar surroundings it could find itself in,” said Inspector Paul Peatfield of Nottinghamshire police.
