A CONVICTED sex offender breached notification requirements by opening an account on the dating app Grindr under the name Mr Grumpy Socks which he hadn t registered with the police. Blackburn magistrates heard Stephen Hughes, formerly known as Stephen Barcelotti, told police he had used the bogus name because he didn t want his former partner to know he was back on the dating scene. And he admitted he had had sexual relationships with two men as a result of his use of the app.
