Kentix's original version "fled the state", is an excellent example of the transitive use of "flee".And does this example work with "from"?
"When he heard the police were looking for him, he fled from the state."
We flee from war, but we flee a state that oppresses us.
I have not yet worked out the reason for this difference. Maybe the answer will come to me later.

Edit
I think it is that we flee a fixed situation, but we flee from an activity or antagonist, e.g.
He fled from the police, and then fled the country.
This not a cast-iron rule (there are few of those in English) but it is a good guide in my opinion.
