US law enforcement authorities have turned their attention to tracking down remaining fugitives in their prosecution of Betonsports, the internet gambling company, after the recent arrest of founder Gary Kaplan.

Top of the wanted list is Norman Steinberg, Mr Kaplan’s alleged business partner. Mr Steinberg, 57, “owned and operated” sports betting websites with Mr Kaplan that Betonsports bought outright in 2004 with money raised in its initial public offering, a justice department indictment says.
