The Cumberland County District Attorney’s Office has dropped a criminal trespassing charge against the president of Smiling Hill Farm.

Warren Knight was arrested in September after refusing to move farther away from a quarry in Westbrook where Pike Industries was scheduled to blast rock.

Knight, an outspoken opponent of Pike’s blasting at the Spring Street quarry next to his family’s farm, pleaded not guilty in November.

The district attorney dismissed the case on Thursday, according to court documents provided by Knight on Tuesday.

Knight was arrested Sept. 28 on Central Maine Power Co. property, between Pike’s quarry and Smiling Hill Farm. He said at the time he was trying to experience the effect of the blast, but was told by police to move onto his own property because he was too close to the quarry.

He refused and then was arrested, taken to Cumberland Country Jail and released on $60 bail.

Knight has argued that the buffer between the quarry and the farm is insufficient.
