A former Royal Navy pilot who stalked his ex partner for years has been jailed for five-and-a-half years.
Kim Allison had already been sent to prison twice for harassing businesswoman Nancy Galloway but carried on as soon as he was released.
Allison, from Yeovil, spied on her by hacking into the website of her bridge club in Torbay, posted a profile of her on a pornographic website and sent her a Christmas card from prison, Exeter Crown Court heard.
Allison denied stalking and three counts of breaching a restraining order but was found guilty by a jury last month.
He was jailed by Judge David Evans, who also imposed a new restraining order which bans any contact and prohibits him entering large areas of Torbay.Copyright: Devon and Cornwall Police
