A repeat child sex offender who sent explicit messages to a police officer posing as a 13-year-old girl and been jailed for 18 months.
Details of how Graeme Murray Purvis, 57, who has a long criminal history of child sex offending, was caught have been revealed at Christchurch District Court where he was sentenced today.
Purvis set up an account with online social network Chatiw in June this year and contacted a 13-year-old girl, who was actually a detective with the Online Child Exploitation Across New Zealand Team.
Using Google Hangouts, Purvis then sent the undercover officer a link where they exchanged more than 500 messages, many of them explicit.
