TWO teenagers were threatened with a knife during an attempted robbery on a c2c train.

On November 7 a group of young men attempted to rob two 16-year-old boys at knifepoint on the train from Chafford Hundred and Upminster station at around 8.30pm.

Thankfully, nothing was stolen.

British Transport Police have released a CCTV image of a man they want to speak to in connection with the crime.

It follows several incidents across London underground stations where several passengers were robbed.

Det Chief Insp Sarah White from British Transport Police said: "Recently we have seen a concerning amount of robberies across the rail network in London, and we are working tirelessly to catch those responsible.

"We have specialist plain clothes officers operating across the network, and passengers can also expect to see highly visible reassurance patrols across key routes and areas.

"However, I would still like to remind everyone of the need to be aware of their surroundings when travelling, particularly in the evenings, and of being discreet and secure when carrying their property where possible.

"Typically, we are seeing things like phones, laptops and Airpod earphones being targeted by groups of young men. They will usually approach people travelling on their own, but many of these incidents have still taken place in crowded and busy areas.

"Thankfully we police a CCTV rich environment which has enabled us to quickly identify a number of suspects and bring them into custody, and I’d now like to appeal for your help in identifying the men in these photos.

"Crucially, the travelling public are our eyes and ears and I would also ask that anyone who notices anything suspicious or that doesn’t feel right to trust their instincts and text us discreetly on 61016, or to call 999 in an emergency.

"If you recognise any of the men in the CCTV images please text 61016 or call 0800 40 50 40 quoting 334 of 14/11/19."
