A HAIRDRESSER secretly filmed himself having sex with his married lover and then sent her children the footage when she dumped him.

Justin Sears, 42, of St Barnabas Road in Woodford Green, terrorised the mother-of-four with more than 10,000 silent calls from 101 east London payphones and even forced his way into her car and cut her hair almost to the scalp.

Over an 18-month period Sears conducted a vindictive campaign including a frenzied attack in March, 2007, when he punched and scratched his former flame before slamming her face into her steering wheel and holding a knife to her throat.

He was jailed for 20 days last year for sending degrading text messages to the victim and again for three-month for slapping her across the face in front of her two young sons.

But still Sears continued his crusade of hatred.

Wood Green Crown Count heard that he threatened to distribute the explicit DVD to his victim's son's school shortly before his barmitzvah and had already sent a copy to her two older children.

Judge Anne Molyneux sentenced Sears to two years in prison after he pleaded guilty to harassment and two charges of assault.

He also had an indefinite restraining order imposed against him and was instructed to attend an integrated domestic abuse programme for two years.

Judge Molyneux said she reduced the term as Sears was the main carer for his 80-year-old invalid mother and also had a disabled son.

The Guardian has agreed not to reveal the name of the victim - who comes from a traditional Jewish background - to spare her family any more anguish.

Investigating officer Detective Sergeant Yasser Awad said: "Sears mounted a systematic campaign of harassment and abuse, causing the victim and her family, including her young children, great distress.

"Sears continued to offend while he was on conditional bail imposed by the courts for other offences against the victim and showed no remorse for his actions.

"I can only hope that the sentence imposed will prevent him from carrying out any further offences."
