A hapless couple who found themselves locked inside a museum after closing time thought to call the police for help - only to be accused of being hoaxers.

Stephen Robinson, 48, and his wife Michelle, 44, from St Helens, Merseyside, were enjoying a visit to Madame Tussauds in Blackpool when they suddenly noticed the venue had emptied and the lights were turned off.

As they attempted to leave, they were left with the disquieting feeling that 'all the exits' had been locked - and they could have to spend hours with only waxworks of the rich and famous to keep them company.

To make matters worse, the pair triggered the alarms inside the building. They attempted to bang on the door and wave at passersby from the windows - but one unknowing bystander simply waved back at them without realising their plight.

Panicking that they could be detained there for a while, the pair called Lancashire Police, only to be met with disbelief.
