A British judge said police have to give Grant information that was allegedly gathered by a private investigator working for the News of the World.
Grant, who says he was told his phone was broken into by the /*News of the World*/, has been one of the most prominent celebrity critics of the 168-year-old tabloid, which was shut down earlier this month amid a widening scandal over its misdeeds.
Police declined comment Wednesday.
