THEY may not be aware of it, but 725 babies somewhere in the world are probably cruising around in pushchairs which fell off the back of a lorry. Six months after a large consignment of toddler's buggies vanished from the back of a truck in Pat Heung, Yuen Long, police are scratching their heads for leads. Asked where he thought the prams might have come to rest, Inspector Kan Kwok-ting said: 'I don't know. If we knew we would not ask the press for assistance.' At about 10.30 pm on June 9, a driver parked his container lorry, loaded with 725 prams, on Fan Kam Road near Hung Mo Tam. When he returned next morning, the lorry was gone. It was found empty the same day under a flyover in Shek Wu Wai Road, Lok Ma Chau, suggesting the $190,000 worth of prams may have been taken over the border. But Inspector Kan said there was no firm indication the Graco buggies had been taken to China. 'Obviously we have informed our border crossing points to pay attention to such cases,' he said, adding shops had also been alerted. Inspector Kan said he had only recently received the case and was not sure if Chinese police had been informed. 'We will have to check the files to see if this has been done,' he said. Members of the public seeing the Navigator-type prams should call Pat Heung police on 2483 8216.
