Thomas Brown, an Elkton lawyer representing Brigham, said he had not seen the charging document. He said Maryland authorities reneged on an agreement to let Brigham voluntarily surrender.
"It is my opinion that Dr. Brigham's arrest . . . was orchestrated to ensure that he remained in custody over this holiday weekend," Brown wrote in an e-mail.
Riley's lawyer, Sharon Krevor-Weisbaum of Baltimore, said, "We have not seen any paperwork. We think it's inappropriate for her to be held. . . . She's not a flight risk."
A Cecil County, Md., grand jury spent 16 months investigating the doctors. Cecil County prosecutors did not return calls seeking comment, and Elkton police offered no information beyond a brief news release.
Brigham's arrest was applauded by those on both sides of the abortion debate.
The Rev. Frank Pavone, national director of Priests for Life, based in Staten Island, N.Y., said in a news release, "These two individuals are now where they belong and should be in jail for the rest of their lives."
Elizabeth Barnes, director of the Cherry Hill Women's Center, said, "I am glad that a predator is off the street."
She added: "I hope the public understands that Steve Brigham is an anomaly and that most abortion care is of high quality."
Barnes is among numerous abortion providers who have filed complaints with regulators about Brigham and his Voorhees-based company, American Women's Services (AWS), which has clinics in New Jersey, Pennsylvania, Maryland, West Virginia, and Florida.
In a June 2009 letter to New Jersey's medical licensing board, Barnes detailed her suspicions that Brigham was starting third-trimester abortions in Voorhees and finishing them in a clandestine clinic.
