Two British tourists told yesterday of their ordeal at the hands of American anti-terrorism authorities during a long-awaited trip to New York.
They claimed they had been "traumatised" by the "heavy-handed over reaction" of the police when they tried to re-enact a scene from one of their favourite movies.
Ken and Liz Bonkers, of Harlesden, north London, had saved for months to visit The Big Apple.
"We'd always wanted to go since we saw Ghostbusters," said Ken. "We especially wanted to go into the basement of the Public Library on Fifth Avenue to see the lady ghost who turns into a snarling monster."
"We even had our own replica proton packs which we were going to subdue the phantom with," Liz added. "I made them with cereal packets and bits from old vacuum cleaners. We really looked the part."
But things started to go wrong when they ran into the library and demanded access to the basement.
"Security started shouting something about terrorists attacking the building - but we didn't see any. Then some policemen started pointing guns at us and shouting at us to get on the floor," said Liz.
The Bonkers were arrested and questioned for 36 hours by NYPD anti-terrorist officers before being released and deported.
"The police's heavy-handed treatment has really traumatised us. Our Lizzie has to take tablets for her leg." said Ken.
A spokesman for the NYPD said: "Mr and Mrs Bonkers put the lives of several innocent citizens, and their own, at risk with their childish antics. They are clearly deluded individuals - everyone knows the ghost was exorcised following the movie's release and now lives on the Upper East Side."
