Waterbury has its first new mayor in a decade.
Shortly after midnight on Thursday, Neil M. O'Leary was sworn in as mayor in a brief ceremony at City Hall, the Republican-American reports.
O'Leary, the former police chief, took the oath of office from Chief Justice William J. Sullivan of the Connecticut Supreme Court. A citywide inauguration is scheduled for Friday.
O'Leary promised to work "very, very hard," and referred only in passing to the campaign in which he beat the incumbent, Michael Jarjura. He called the campaign a "little rough."
Jarjura served five terms. He unsuccessfully sought re-election as a Republican after the Democratic Party rejected him and instead backed O'Leary.
