It looks dramatic – smoke billowing out of the Boots shopfront on Wanstead High Street, while people huddle on the pavement not knowing what to do.
But it’s not quite what it seems. For the second time in two months, a security system which pumps dry ice into the shop to befuddle intruders has gone off, making passers-by think something disastrous is going on. But all’s well – the ‘smoke’ cleared and the shop opened as usual.
