FLEET <FLT> COULD FACE CONNECTICUT DIVESTITURE Fleet Financial Group said it might have to sell its First Connecticut Corp subsidiary as a result of its proposed 1.3 billion dlr acquisition of Norstar Bancorp <NOR>. Under Connecticut banking law, New England based bank holding companies such as Fleet are not allowed to operate Connecticut banks if they merge with companies from outside the region. Norstar is based in Albany, N.Y. First Connecticut has assets of about two billion dlrs. Fleet has total assets of about 21 billion dlrs. Fleet said it will seek to have the Connecticut law amended to allow it to retain First Connecticut, which is based in Hartford. Fleet's acquisition of Norstar is now expected to be completed around July 1, 1988, when a change in laws in Fleet's home state of Rhode Island allowing interstate banking outside New England will go into effect.
