A MYSTERY street sign has appeared in an alleyway and ­residents are wondering what it can mean.

The red and white sign in Miller Street, Camden Town, appears to show a person with an umbrella who is desperate for the toilet.

Rachel ­Cottrell, who lives nearby, said: “It’s a very convincing replica, presumably indicating that one may shelter here but not expect to find toilet facilities. There is no mention of this on any website and local people may be equally amused by it.”
