The Mounties bombed an oil installation as part of a dirty tricks campaign in their investigation into sabotage in the Alberta's oil patch.

The revelation came at the bail hearing Thursday of two farmers who the Crown says have turned their complaints that oil industry pollution is making their families ill into acts of vandalism and mischief.

Their lawyer produced evidence that the RCMP bombed a wellsite and that they did it with the full support of the energy company that owned it. The Crown admits the allegations are true.

The police have been under pressure from the industry and the government to put an end to two years of attacks which have caused millions of dollars in damage.

Lawyer Richard Secord told Court of Queen's Bench that when Alberta Energy Co. and police blew up an AEC shed last Oct. 14, they blamed it on his client, farmer Wiebo Ludwig.

Secord also claims AEC offered to buy a neighbour's property for $109,000 if he gave them information about Ludwig.

Ludwig and Richard Boonstra face nine charges involving vandalism at energy installations.

They were denied bail.
