Went looking for a local newspaper account online because I thought I had heard a radio report last night say the fan had tried to choke the ref with his whistle lanyard. Apparently true.
More good details from the incident, esp. from the official, here:

Have to love the line, "You can't arrest me, you're a referee!"
