WICHITA, Kan. - An abortion doctor returned to work yesterday less than 12 hours after being shot, and his alleged attacker - a homemaker active in the anti-abortion movement - was in custody.

Wearing bandages on both arms, Dr. George Tiller arrived at Women's Health Care Services at 7 a.m., stopping outside to thank those who tended to him after Thursday evening's shooting.

About a dozen abortion-rights activists showed up at the clinic and heckled a half dozen antiabortion protesters.

Rachelle Renae "Shelley" Shannon, 37, of Grants Pass, Ore., was arrested early yesterday at the Oklahoma City airport in connection with the shooting.

The Sedgwick County district attorney's office in Wichita filed an attempted first-degree murder charge yesterday and faxed a warrant for Shannon's arrest to Oklahoma City authorities, a spokeswoman said.

Shannon waived extradition in a 10-minute hearing in Oklahoma City late yesterday and was being returned to Wichita.

"She inquired about the doctor that got shot. She seemed relieved to hear that he had not been seriously injured and she inquired if he went to work today," said Bert Richard, an assistant public defender.

Shannon had a white hood draped over her face at the request of Wichita authorities.

Peggy Jarman, spokeswoman for Tiller and the ProChoice Action League, said yesterday: "I knew if there was any way possible for him to be at work he would be. I had hoped he would take a couple of days off, but that was unrealistic of me."

Tiller, 52, was leaving his east Wichita clinic Thursday evening when a woman who had been mingling with protesters near its driveway approached his vehicle. Witnesses said she fired four or five shots from a small-caliber, chrome semiautomatic pistol.

Clinic employees followed the woman and got a description of her car and a license number, police said.

After 45 minutes of surgery under local anesthetic, Tiller was released from HCA Wesley Medical Center. Jarman said one wound was superficial and the other involved muscle but not bone damage.
