A former officer in the uniformed division of the Secret Service, who allegedly led a controversial late night White House tour, was sentenced yesterday to three years of probation after pleading guilty to taking a piece of White House china.

Reginald A. deGueldre, who authorities said resigned from the Secret Service in connection with his May guilty plea, also was sentenced to perform 100 hours of community service.

DeGueldre was in the news in 1989 for allegedly taking the late Washington lobbyist Craig J. Spence and others on a midnight tour of the White House.

In imposing the sentence in U.S. District Court here, Judge June L. Green said she gave favorable consideration to matters that included the absence of any previous record, the fact the china was returned and deGueldre's ability to contribute through community service.

His attorney, Mark Tuohey, called deGueldre's offense "an error in judgment" to which he admitted and "not anything more serious . . . . "
