Following a head-on car
accident in which one driver was seriously injured, the cause
was established by police as a diesel spillage on the road surface.
It was traced to a leaking diesel return pipe on a recovery vehicle
(image above). Examination showed that the fuel return pipe had
been cleaved across radially, and the Forensic Science Service
attributed the failure to a knife-wielding vandal.
