British Columbia MLA Pat Pimm has been charged with assaulting his wife, Jody Cooper, on Aug. 13, according to documents filed in provincial court.

Pimm, 59, who represents Peace River North, was arrested last month and stepped down from the Liberal Party caucus over the then unspecified allegations.

Six days after the alleged assault, which occurred in or around Dawson Creek, a Supreme Court family law proceeding was initiated involving Pimm. The file is sealed from public access — as is the normal procedure.

The politician is scheduled to appear in Dawson Creek provincial court on the assault charge on Sept. 13.

Pimm was first elected in 2009 and appointed agriculture minister in 2013, before leaving cabinet last year to seek treatment for colon cancer.

He was arrested in connection with a domestic dispute involving his wife in 2011 and returned to the Liberal caucus after a special prosecutor decided no charges would be laid.
