Newly released court documents say Rob Ford's sister told police the Toronto mayor was smoking crack cocaine with her one night in April in the company of a drug dealer and another man who is facing drug charges.

The documents released Wednesday by a judge say Kathy Ford was twice interviewed by investigators after reports surfaced last May of a video allegedly showing the mayor smoking crack in his sister's basement.

Police say they believe the video was recorded on April 26 by Michael "Jugga" James, whom Kathy Ford said sold drugs to her and her brother that night. She also said Ford was drinking with his friend, Alexander Lisi, who is facing drug charges.

Ford last week dropped his bid for re-election after being diagnosed with cancer.
