Police investigating the death of 15-year-old Josh Reeson have pieced together more details about his last movements.
And they are renewing their appeal for witnesses to get in touch.
Josh was taken to York Hospital by ambulance shortly before 4am on Sunday, 27 September, where he died later that day after having taken illegal drugs.
Officers now know more details about the whereabouts of Josh and his friend prior to the call for an ambulance.
Josh and his 14-year-old friend left an address on Fulford Road around 3.10-3.15am and from there they walked down Fulford Road towards town. They then doubled back slightly and went down Broadway West.
The two boys then walked back on to Fulford Road, where they met a 14-year-old female friend near to the junction of Maple Grove.
It is at this point, on the junction of Fulford Road and Maple Grove that Josh became ill. A relative of Josh’s friend called the ambulance and stayed with him until it arrived.
Officers are appealing to anyone who thinks they might have seen the teenagers in the area between 3am and 4am, or anyone who was driving in the area at the time and may have dashcam footage, to contact North Yorkshire police.
