The fight over Citadel Holding intensified.

Dissident shareholder Alfred Roven announced that he has stepped up his proxy fight to win board representation and change bylaws at the Glendale-based savings and loan company. Roven, who controls 9.1% of Citadel’s common shares, is seeking shareholder approval to delay the annual meeting, set for next week, and alter various anti-takeover provisions. Roven wants to see Citadel sold to a third party. Meanwhile, the investment banking firm of Goldman, Sachs revealed in an SEC filing that it had boosted its stake in Citadel to 9.7% from 8.4%, apparently betting on an imminent takeover. Citadel management said it is talking to “several” possible suitors.
