A jilted boyfriend who held a secret 10-year grudge against his school sweetheart created fake social media accounts in her name to get revenge.
Masquerading as her on social media, Thomas Berry, 26, would send random men suggestive messages and promised to send them naked photos.
His "long-standing obsession" with Ellie Steele continued for years despite no other contact, after she dumped him when they were 16, the court heard.
