Operation Lepus has been re-launched as conditions become conducive to the illegal practice taking place.

Drier weather in recent days has allowed farmers the opportunity to cut their crops and hares can be easily seen across many field in Perth and Kinross and Angus.

This makes ideal conditions for hare coursing, an activity that was completely banned in Scotland from 2002 under the Protection of Wild Mammals (Scotland) Act 2002.

Alan Stewart, Tayside Police wildlife and environmental crime officer, said:

"Our message to those who are determined to ignore the law and chase hares with dogs is that police officers will use all powers at their disposal to tackle this illegal practice.

"They should be aware that we can take action even if a hare has not been caught, or even seen to be chased by dogs. The very fact that they are out searching for hares to course is sufficient evidence to prosecute. They are likely to be arrested and can expect a court appearance.

"The police receive excellent support from farmers, landowners, gamekeepers and other country residents. They report incidents to us in the knowledge that we will act, even if those responsible have disappeared by the time they arrive.

"There have been several convictions in past years and this offers reassurance to landowners or tenants of the land where the incidents have happened that positive action is taken by the police, by procurators fiscal and by the courts."

Anyone who is detected hare coursing can - as of earlier this year - face a fine of £10,000 (previously £5,000) and also six months imprisonment.

Mr Stewart said: "I would encourage anyone who sees hare coursing taking place, or is suspicious about the behaviour of people with greyhound-type dogs (whether on foot or in cars) in quiet rural areas, to phone the police immediately.'"

Anyone who has any information about people who are involved in, or who they suspect to involved in, hare coursing or poaching, can call Alan Stewart on (01738) 892650, or provide details anonymously to Crimestoppers on 0800 555 111.
