Masked gunmen on Friday raided the Amsterdam hotel where John Lennon and Yoko Ono held their 1969 bed-in for peace, making off with cash but causing no injuries, police said.
"Two balaclava-wearing criminals entered the hotel just before midday," Amsterdam police spokeswoman Marjolein Koek said of the raid on the Apollolaan Hilton, to the south of Amsterdam's city centre.
"Using the threat of weapons they stole an as-yet unknown amount," she said. "They fled in a black Volkswagen Golf."
The hotel declined to comment when contacted.
Beatle Lennon and his artist wife Ono made the hotel world-famous when in 1969 they used media interest in their marriage to promote world peace by spending their honeymoon at the hotel.
At the height of the Vietnam War, the couple invited the world's press to visit them during their week in bed in the hotel's presidential suite.
