"Incredibly dangerous" booby traps have been found on popular cycle
paths in the Peak District.

Items found in recent weeks include large rocks moved out of position,
pins dropped on the road and branches arranged at head height across paths.

Chris Maloney, who runs a local cycling information blog, said while
cyclists appeared to be the target, the obstacles could harm anyone.

Police said they had been made aware and appealed for information.

The traps have been spotted on trails and roads in Bradwell, Bamford and
Aston, near the Derbyshire/South Yorkshire border. There are no reports
of anyone being injured.

Unless you videoed them placing caltrops on the path it might be difficult to prove much in court.
