At-large Councilman Michael Brown said Thursday that a staff member embezzled money from his campaign bank account, the latest allegation of financial impropriety leveled against a member of the city’s embattled political establishment.

“I discovered information which indicated that unauthorized disbursements had been made from the campaign bank account by an individual who has assisted my campaigns for over five years,” Brown said in a written statement. “Upon discovering this disturbing fact, I immediately contacted the Metropolitan Police Department.”
