A D.C. Superior Court judge yesterday denied bond for Shao T. Hsu, 66, a University of Maryland professor who is one of the Washington area's most controversial landlords.

Hsu is being held in D.C. Jail after his conviction Friday on a perjury charge stemming from a 1975 civil court hearing concerning one of his Southeast D.C. properties.

Hsu faces a maximum 10 years in prison on the conviction.

Judge Peter H. Wolf denied Hsu's request for bond, saying that Hsu, who last year allegedly offered to "take good care" of the prosecutor in the case, Assistant U.S. Attorney David S. Krakoff, in exchange for a favorable plea bargain, had failed to show that he would not pose a danger to the community if released.

Hsu's attorney, Jeffrey Lee Greenspan, had sought Hsu's release on bond, arguing that Hsu suffers from high blood pressure and that he needed to teach his classes at the university.

Hsu is being held in a protective isolation cell at the jail, at Greenspan's request. Greenspan said he may ask the D.C. Court of Appeals to review Wolf's ruling on a bond.

In other action yesterday, University of Maryland officials said they are awaiting a state attorney general's ruling on possible removal of Hsu from his position as a tenured professor of engineering.

Wolf's ruling yesterday followed a private bench conference with the prosecutor and Hsu's defense attorney, the record of which Wolf later ordered sealed.

Wolf, speaking through an aide, declined late yesterday to comment on his order to keep Hsu in jail until sentencing April 20, saying only that information presented at the bench conference contains "potential [information] for a criminal investigation in a matter that is not necessarily related to Dr. Hsu."

Hsu, who has been convicted numerous times of housing violations, originally was convicted on the perjury charge in 1976 after he disputed in court testimony the previous year that he had been served with an order to make improvements at the Southeast property. A lawyer testified he served Hsu with the order.

The 1976 conviction was overturned on grounds that Hsu, who represented himself at the trial, had been inadequately represented.

A University of Maryland spokesman said yesterday that a perjury conviction constitutes "moral turpitude" and is an offense for which a tenured professor may be removed.

"The question is whether the appeals process has been exhausted," the spokesman said.
