Speaking yesterday, a spokesperson for Derbyshire Constabulary said: “Two males caught poaching from the Lock Bridge in Bakewell last night (20/07/2022) both males have been reported to the Environment Agency for fishing without a valid rod licence.
"Both had their fishing equipment seized at the riverside, so they could not do anymore fishing.
“One of the males was arrested at the scene for being unfit to drive through drugs (Drug in charge of a motor vehicle.) Pretty expensive fishing trip!
“Thanks to our local river keepers for looking out for these people and protecting local wildlife for everybody to enjoy.”
