Mayor Adams on Friday named his younger brother as a deputy NYPD commissioner, police sources said — a move that immediately raised conflict-of-interest questions. Bernard Adams was assigned to the office of new Police Commissioner Keechant Sewell, sources said. The post — which comes with a yearly salary of around $240,000, according to SeeThroughNY.net — is believed to be temporary. Sources expect Bernard Adams to be transferred elsewhere once other high-level personnel moves are finalized.
