Police said Sunday that there is no record of a missing British woman leaving Japan, after the British Broadcasting Corp. reported Saturday she was witnessed at a cash machine in Hong Kong following her disappearance from a Tokyo apartment in July.

Police said there is no record of Lucie Blackman, 22, leaving Japan, adding her passport was left behind.

The BBC report quoted a tourist as saying that sometime between July 16 and 18, he saw a woman at the cash machine who looked similar to a photo of Blackman that appeared in Hong Kong's China Morning Post.

Her father had earlier received information that Blackman was smuggled to Hong Kong as part of the illegal sex trade, the report said.

Lucie, who worked as a hostess at a bar in Tokyo after arriving in Japan in May, went missing after leaving her apartment in Tokyo's Shibuya Ward on July 1, telling a friend she was going to meet someone.

A reward of 100,000 British pounds ($145,000) has been offered for information about her whereabouts.
