Swedish twins involved in a shared psychotic episode
Ursula Eriksson and Sabina Eriksson (born 3 November 1967) are Swedish twin sisters who came to national attention in the United Kingdom in May 2008. They had been in Ireland before travelling to the UK and boarding a bus for London in Liverpool. Their odd behaviour after exiting the bus at a service station on the M6 motorway caused the driver to not allow them back on board. The two were later seen on the central reservation of the M6 motorway. When Highways England traffic officers arrived to assist the women, they ran across the busy motorway, as captured by a small television crew.
