Disgraced tennis star Bob Hewitt was suspended indefinitely from the International Tennis Hall of Fame Thursday, following a lengthy investigation into allegations that he sexually abused underage girls he coached, from Greater Boston to his South African homeland, from the 1970s to the early 1990s.

The Hall of Fame stopped short of expelling Hewitt, one of the greatest doubles players in tennis history, because he has not been convicted of a crime, according to executive director Mark Stenning.
