Two robbers have been jailed for 33 months for forcing an “absolutely terrified” teenage boy to travel by train to a cashpoint before taking his money and an iPhone.

But their younger accomplice was spared jail over the false imprisonment and robbery during the evening rush hour on Friday, February 28.

The 17-year-old victim, who cannot be named for legal reasons, was taken prisoner on the platform at Epsom station and made to get on a train to a cashpoint at Clapham Junction station.

He was forced to withdraw £80 in cash and taken back to Ewell West station. On the first train the ringleader showed the teenager a handle, which he assumed was a knife, and the ordeal lasted an hour.

At the time the youngest robber sent a text message saying: “We have kidnapped some boy lol. He’s taking us to a cashpoint in Clapham Junction."

Blackfriars Crown Court today handed down jail terms to Christopher Amirjani, 23, of no fixed abode, and Marcus Idahosa-Easy, 18, of no fixed abode, who was referred to as Easy during the case.

A 17-year-old, who cannot be named for legal reasons, was given a two-year youth rehabilitation order, 40 hours of community work and supervision for two years. He must pay £500 to the victim in compensation.

Easy had pleaded guilty to robbery of £80 and an iPhone on the basis that his pleas would encompass a false imprisonment charge which was left to lie on file.

Judge Daniel Worsley told him: “You were the instigator, the leader and by far the most aggressive and intimidating at all stages. It would never have happened without you.”

Mr Worsley said on the train Easy discreetly flashed a handle kept his pocket and the victim believed that he would be stabbed if he tried to escape.

He said: "These are very serious crimes. Your victim was not only young, he was specially vulnerable because he had an obviously injured face which your co-defendant asked him about.”

He added: "He was absolutely terrified and that terror remained with him and his family well after the offence."

He said Easy had been in “criminal trouble” since the age of 13 when he was caught with a knife, and he went on to commit disorder offences, two robberies and a burglary.

Although Easy avoided custody, he continued to take drugs and he was on police bail and subject to a youth rehabilitation order when he instigated the robbery in February.

His defence lawyer Flora Page said he had been drinking and smoking cannabis that day and may have been trying to impress his older companion.

Ms Page said: “Apart from that, it was a very nasty incident and Mr Easy sees and recognises that now and extends his remorse through his guilty pleas."

She said he had made good progress in custody, had not sought to minimise or play down what was a “very unpleasant” experience for the victim and sincerely apologised to him.

She said: “Mr Easy is somebody who has a lot of good in him as well as the bad that has come out in offending.”

Amirjani, who has a previous conviction for robbery, was found guilty of false imprisonment and robbery of £80 and an iPhone at the end of a trial in September.

On the platform in Epsom he intimidated the victim by leaning in and saying: “Don’t worry, we ain’t going to touch you. We just want your stuff.”

Mr Worsley said: “Your blame for the offence is significant, but less than that of Easy.”

He added: “You knew what you were doing, you were part of the team. It sticks in the gullet as a matter of justice that you end up with a longer sentence than Easy.”

The youngest robber, who sent the text message saying they had “kidnapped some boy”, was convicted of false imprisonment and robbing £80 after a trial.

Mr Worsley said he acted as “back-up” and was intimidated himself.

He said: “Nobody wants anything but you to go the right way in the future for your child, for your girlfriend, for the community."
