British Transport Police are trying to track down two men who robbed two boys, 16, on a train.
Officers have released CCTV images of the two men they want to speak to in connection with the incident on a train between Romford and Upminster on Thursday, October 17.
The teenagers, from Chafford Hundred, boarded a train at Romford at about 7pm.
During the journey two men also boarded at Romford and approached them, demanding they hand over their belongings, including phones, wallets and keys.
Detective Constable Michael Hatcher, the investigating officer, said: “The men threatened them, claiming they had a gun – although no gun was seen - before grabbing one of the boys round the neck.
“Fearing for their safety, the two victims handed over their mobile phones, a passport and headphones.
“As the train arrived into Emerson Park station, the two teenagers left the train before reporting the incident to a local police station.”
Officers are currently carrying out a number of enquiries into the incident.
DC Hatcher added: “The men targeted two young men and used violence to take their belongings. We are continuing to build a full picture of exactly what happened, and I’d urge anyone who recognises any of the men to come forward and assist in our enquiries.”
The men are believed to have links to Stanford-le-Hope.
Anyone with information is asked to contact British Transport Police on 0800 40 50 40 with the reference B3/LNA of 29/10/2013.
Information can also be given to Crimestoppers, anonymously, on 0800 555 111.
