LONDON (AFP) - British army bomb disposal experts were called in to the city of Canterbury and the centre was partly evacuated after the discovery of a suspect package, but the device was a hoax, police said Saturday. Police were also investigating a suspicious fire at a shop and reports of suspicious activity at the cricket ground in the historic city in southeast England. It was not known if the incidents were linked. The package was discovered by a member of the public on a railway line, prompting emergency services to halt trains and lock down the centre of the city, a popular tourist destination famed for its ancient cathedral.
