A jilted boyfriend who lured his former girlfriend to a bogus job interview has had his jail sentence more than doubled at an appeal hearing.

Gym instructor Nasar Munir was given a harassment warning last November in relation to his former girlfriend Faiza Akram, but earlier this year he set up a mock company to use as a cover so he could send her an e-mail inviting her to a job interview near her home in Buckinghamshire.

Bradford Crown Court heard yesterday that the 22-year-old Bradford man then travelled down to the Aylesbury area the night before the “interview”and the next day he confronted his unsuspecting victim.

Prosecutor Imran Khan told a judge and two magistrates how Miss Akram, who had previously been in a six-month relationship with Munir, feared for her safety when she saw him and sought help from members of the public.

During the incident in February Munir threatened to smash the legs and jaw of witnesses if they telephoned the police and at one stage there was allegedly a remark about him having a gun.

After an argument with Miss Akram, Munir left in his Audi A6 car, but he was tracked down using an automatic number plate recognition system.

Munir, of Cottingley Road, Allerton, initially told police the meeting was a coincidence, but later confessed to setting up the bogus interview scam because he knew the complainant was unemployed.

Barrister Abigail Langford, for Munir, said the couple’s relationship had ended suddenly and her client was upset.

She said there was a suggestion that Miss Akram’s family did not consider her client suitable for the complainant.

Miss Langford submitted there was confusion about the reference to a gun and she said at one stage her client remarked: “I’m not going to kill her she’s my ex.’’ Munir pleaded guilty at hearing before Aylesbury magistrates to a public order offence of putting someone in fear of violence and was jailed for eight weeks.

But when he appealed that sentence in front of Judge Jonathan Durham Hall QC and two magistrates today they decided that his jail term should in fact be increased to five months.

‘’It will come as no surprise that our joint view of this shocking incident is that your actions were unbelievable and in many ways chilling,’’ the judge told Munir.

‘’This bench collectively has rarely encountered a Section 4 prosecution with so many aggravating features.’’ The judge said Miss Akram’s reaction on seeing Munir was to seek the protection of other members of the public and his reaction was to threaten serious violence.

Judge Durham Hall said the case had sinister and chilling features and he also imposed an indefinite restraining order to stop Munir contacting his victim again in the future.
