NEW YORK -- A physician caught on videotape offering to perform cosmetic surgery after his medical license was revoked pleaded guilty Wednesday to the unauthorized practice of medicine and assault.

Dr. Jose A. Lopez, whose license was lifted in October 2003, was arrested in May 2004, a few weeks after he offered to do liposuction on a woman in his office, Aesthetic Concepts Laser Surgical Center.

Lopez, 42, pleaded guilty in exchange for a maximum of two to six years in prison when state Supreme Court Justice James Yates sentences him on Jan. 26.

Yates also said he would allow Lopez, who remained free on $100,000 bail, to withdraw his guilty plea to second-degree assault, a felony, and let him plead guilty to attempted assault, a misdemeanor, when he surrenders his Colombian passport.

Prosecutors from the state attorney general's office alleged that Lopez' brother, Wilson, and his wife, Diana, were accomplices in his illegal medical practice.

Lopez' encounter in 2004 with the patient, identified in court papers only as "Lillian," was videotaped without the defrocked doctor's knowledge by a television news investigative team, which turned it over to prosecutors.

Lopez, who also had an office and home in Elizabeth, N.J., was arrested in Miami Beach where he has a home, his lawyer Francisco Hernandez said.

Hernandez said Lopez' New Jersey medical license was revoked permanently in 2003. Authorities there cited the July 2002 death of a woman during a "tummy tuck" operation, and "disastrous" surgeries involving five other patients.
