Police are examining the theory that the pair found dead in the middle of the night after being electrocuted on train tracks near London stadium were railway graffiti artists, MailOnline has learned. Police came across the first victim, a man in his 20s, at 1am and the second at 2.31am, while a witness overlooking the busy morning commuter line in Stratford described seeing flames and smoke on the line. It is not known why the two people were on the tracks and police are yet to determine the second person's gender. The British Transport Police say the deaths are linked and both victims suffered serious burns. The incident took place near West Ham United's 66,000 capacity home ground, which previously hosted the 2012 Olympics. An investigation is now underway to determine why the two people were on the line. Police are also trying to identify the pair so their families can be informed. The incident initially caused closures and disruption on the London Overground and Greater Anglia services but this has now been cleared. Last year, three graffiti artists were killed by a train when they walked down tracks near Loughborough Station in south London. The families of Alberto Fresneda Carrasco, 19, and 23-year-olds Jack Gilbert and Harrison Scott-Hood gave a joint statement saying 'a love of painting' was the only thing they were guilty of. A British Transport Police spokesman told MailOnline today the theory the victims were graffiti artists 'is a line of enquiry', although there is not yet any evidence that is the case. Detective Chief Inspector Tim Tubbs said: 'An investigation is now underway to discover what happened and how these two people came to lose their lives on the railway. 'At this time we are treating their deaths as unexplained as we make a number of urgent enquiries. 'I would ask anyone who was near Stratford or Hackney Wick last night, and saw something which they think might be relevant to contact us as soon as possible.' A BTP spokeswoman said: #tin247
