An elite Rhode Island boarding school embroiled in a sexual-abuse scandal says an administrator has been placed on leave over allegations concerning his conduct as a dorm parent in the 1990s.

St. George's School says in a letter sent to alumni Wednesday associate head for external affairs Bob Weston was placed on leave in January pending the outcome of an independent investigation. The Middletown school says it received "secondhand allegations" regarding Weston's "boundaries with students."

A phone number for Weston has rung unanswered. Weston's lawyer hasn't returned phone and email messages seeking comment.

A school spokesman contacted Wednesday evening said due to the late hour there would be no further comment.

Dozens of former students have come forward alleging abuse dating to the 1970s. An attorney representing many of them says he's aware of more than 50 credible cases.
