A federal employee who police say conducted background checks for U.S. Immigration and Customs Enforcement and other government agencies was arrested last week in a Bloomington prostitution sting. Bloomington Police Chief Booker Hodges said Department of Defense contractor Brashad Johnson, 36, of Maple Grove, was one of 30 suspects arrested as part of an undercover operation targeting people seeking to pay for sex. "This is the most disturbing arrest that we've had here," Hodges said of Johnson during a news conference on Tuesday. "He is a backgrounder for ICE, Homeland Security and federal agencies. So when you're getting your security clearance, this is one of the guys that does your backgrounds, which is kind of scary."
