British Transport Police detectives are appealing for information after a man was robbed of his phone, money and ordered to leave a train at Upminster station.
Investigators have today released CCTV of a man and woman they would like to speak to in connection with the incident, which took place around 9.15pm on Thursday, April 25.
Detective Constable David Bishop, the investigating officer, said: "The victim, a 28-year-old man, was on board a train between Basildon and London, when he was approached by a man and woman.
"As the train was approaching Upminster station, the man snatched a phone from the victim's hand. The man then continued his attack by forcing the victim to empty his pockets, where he handed over five pounds in change.
"He then aggressively told the victim to get off the train at Upminster. Fearing for his safety, the victim did so whilst the man and woman continued their journey. They are believed to have left the service at Barking."
The victim immediately alerted a member of staff and police, and an investigation was launched. Officers have carried out a number of enquiries to establish the identity of the man and woman, including viewing CCTV from on board the train and from the surrounding area.
DC Bishop added: "This must have been a terrifying ordeal for the victim, who was threatened with violence. We will not tolerate this type of behaviour and we will continue to work to identify those responsible.
"We have clear CCTV of a man and woman that we are keen to speak to following the robbery. If you know who they are, or indeed are the pair, I'd urge you to contact police and assist in the investigation."
Anyone with information is asked to contact British Transport Police on 0800 40 50 40.
