SEATTLE (Reuters) - A private investor has proposed building a new sports arena in Seattle, raising $290 million in private financing for the facility, with the aim of drawing professional basketball and ice hockey teams to the city, municipal officials said on Thursday.

The plan from investor Christopher Hansen, described by the Seattle Times as a San Francisco-based hedge-fund manager and Seattle native, calls for his investor group to bear the costs associated with acquiring a National Basketball Association (NBA) team.

The group would seek a partner who would recruit a National Hockey League club to the new facility, city and King County officials said in a joint statement.
