A Norfolk man, who posed as a professional photographer to lure two women to his home, has had his jail term increased.

Calvin Edwards, of Greenacre Road, Hingham, had been jailed for four years at Norwich Crown Court on July 29, after pleading guilty to administering a noxious substance and attempting false imprisonment.

But at London's Appeal Court today, Jeremy Wright, attorney general, argued that Edwards' jail term should have been tougher.

On January 7 this year, two females went to Edwards' home after seeing an advert for 'models' on a modelling website.

The 33-year-old offered them both a cup of tea but they did not drink it because they were 'suspicious of him' and said it had a 'funny smell'.

He ushered the pair into a living room, which he claimed was his studio, and grabbed one of the woman around the throat and made threats towards the other.

Both women tried to escape and managed to grab some knives from the kitchen and hide in the bathroom, where they called the police.

Officers found a rucksack containing items, including chains padlocked to form manacles, leather restraints, duct tape, rubber gloves and a balaclava.

Edwards' term was increased to five years and four months.

Sir Brian Leveson, judge, said Edwards was a 'dangerous' offender and ordered him to serve an extra three years on licence following his release.

Speaking after the hearing, the Solicitor General Robert Buckland QC MP said: 'This was a carefully thought out and calculated plot. It seemed to me that offences with this degree of planning required a harsher sentence, and I'm glad to see the court has ruled that Edwards should spend longer in prison.'
