Deborah found an animal in distress, but she was then accused of a theft

her two weeks ago to say they would not be submitting a report to the Procurator Fiscal to consider criminal prosecution.

Deborah – who does not know how the police got the information which enabled them to trace her – said the whole incident was concerning.

“I was astonished by the charge,” she said. “Pursuing me was a warped decision.”

Snares such as the one Deborah discovered are illegal in many European countries.

However, they are legal in Scotland, provided the snare is set properly.

In 2011 the Scottish Government rejected attempts to ban them saying they were a humane way of killing predators such as foxes.

Ministers said the control of predators through snares helped to maintain Scotland’s shooting industry, boosted conservation and helped farmers protect their animals.

In Scotland their use is controlled by the Wildlife and Natural Environment Act. It decrees their use should not inflict any unnecessary suffering.

It also limits where they can be placed and how animals are caught, with many experts interpreting the law to rule out foxes being trapped round the abdomen.

Libby Anderson, of animal protection charity One Kind, said: “A fox shouldn’t be trapped around the abdomen.

“In that case the trap may well be illegal.

“Deborah’s case is an overreaction by the police.”

John Robins, of the Animal Concern Advice Line, believes all snares should be banned.

“They are incredibly cruel to animals they catch, who suffer a slow and painful death,” he said.

A Scottish SPCA undercover inspector said: “We can confirm a member of the public raised concerns with us over a snare after a fox was discovered trapped in the device.

“We investigated the issue surrounding the legality of the snare and no report was sent to the Procurator Fiscal.”

A spokeswoman for Police Scotland confirmed officers had visited Deborah and charged her with theft but had since dropped the charges.

Last night, a spokesman for the Scottish Gamekeepers Association confirmed interference with legal predator control traps and snares was a criminal offence.

He said: “These devices are set by trained professionals for a legitimate legal purpose – to protect vulnerable ground- nesting species from abundant predators such as foxes.

“The benefits of this, from a conservation perspective, are well evidenced in scientific research on predation and its impacts.

“In this case, some leniency seems to have been applied to the person committing the offence. It is highly unlikely the same leniency would have been shown to the operator if he/ she had been accused of an alleged offence involving the traps or snares.”
