The 16-year-old was riding between Howitts Lane and Howitts Gardens, near the railway bridge, at 5.30pm on Friday (April 24). The rope left him with serious injuries to his neck and wind pipe and he was taken to Addenbrookes Hospital, Cambridge, where a police spokesman said he was in a serious, but stable, condition. Detective Constable Diane Tomlinson said: The young man is in a serious condition in hospital and I would like to speak with anyone who may know why the rope was tied to those trees, or who may have put it there. Anyone who uses the area, such as dog walkers, who may have information, no matter how insignificant it may seem, should call police. Anyone with information should contact the Huntingdonshire Safer Neighbourhood Team on 101 or Crimestoppers, anonymously, on 0800 555111.
