KATONAH - The superintendent of schools in the Katonah-Lewisboro School District has abruptly resigned.

Superintendent Paul Kreutzer announced yesterday that he's resigning effective immediately.

The announcement, made on the district's website, comes less than a week after the school board voted to close the Katonah-Lewisboro Elementary School. In the statement, the Board of Education said the decision is due to "irreconcilable differences" between Kreutzer and the board.

Michael Jumper, the assistant superintendent for business, has been named acting school superintendent.
