MEXICO CITY (AP) _ Mexico City police arrested a 23-year-old man Saturday who is suspected of killing a society columnist and her servant two weeks ago.

Officers captured Pedro Saucedo Avendano at a station where he was about to board a train to the southern state of Chiapas, the government news agency Notimex reported.

Sally-Sue Hulse, 60, a columnist for the English-language Mexico City Times, was stabbed to death Aug. 3 in her Mexico City apartment. Her servant, Alberto Chavez, was found beaten to death in a back room.

Police said Saucedo admitted that he had entered Hulse's apartment, near the popular Zona Rosa district, intending to steal valuables and cash. However, Saucedo also said that he and Chavez, 62, had a personal relationship and that they fought before Saucedo killed him, according to police.

Hulse, who was born to British parents in Belize, had lived in Mexico for 47 years. Her column, ``Pulse by Hulse,'' described social events in Mexico City's large foreign community.
