"The Bolton Evening News has launched a bid to track down 999 hoax callers by uploading MP3 recordings of some of the calls to its website. As part of its new Shop A Hoaxer campaign the paper is uploading a new call to its website every day in the hope that readers might recognise the voices. The move is the first time the paper has run a campaign in conjunction with its website, and in the first few hours more than 1,000 people logged on to hear the first call. " [Police News; Technology]
