William Oliver Hughes Jr., 26, a suspect in the murder of a District of Columbia bank teller during a robbery last week, was ordered held without bond yesterday by a federal magistrate in New Orleans, where he had turned himself in to the FBI Saturday.

Hughes will appear again before Magistrate Ingard O. Johannesen Oct. 7 for a removal hearing in which FBI officials expect to be given permission to transfer Hughes back to Washington, according to Joseph P. Schulte, assistant agent in charge of the FBI's Washington field office.

Hughes then will be turned over to D.C. police, Schulte said. An FBI spokesman in New Orleans said that no gun or money was recovered at the time of the arrest. Hughes is being questioned about them, the spokesman said.

Hughes is wanted on a D.C. Superior Court arrest warrant charging him with murder in the slaying of Sonya Grillo Durham, 36, who was shot during a robbery last Thursday at a branch of the National Bank of Washington at 301 Seventh St. NW.

D.C. homicide detectives obtained the warrant Friday after people telephoned to say that they recognized the robber from photos taken by the bank surveillance camera that appeared in newspapers and on television.
