The former CNN anchor Don Lemon and three other people have been arrested on charges that they violated federal law during a protest at a church in St. Paul, Minn., this month, lawyers and Justice Department officials said on Friday, reviving a case that was rejected last week by a magistrate judge.

The arrests of Mr. Lemon, a second journalist and two protesters came a little more than a week after three other demonstrators who took part in the action at the Cities Church on Jan. 18 were taken into custody.
