TOWLEROAD - Jan 20 - One of Manchester's Councillors, former Member of Parliament John Leech, is demanding that dating apps such as Grindr and Tinder will include safety notices to help prevent the troubling number of criminal incidents connected to their use. ~500 criminal incidents across the United Kingdom, including murder, rape and child abuse, 162 of which are listed as sexual offenses, have been linked to both Grindr and Tinder.
