Three facilities managers for the Boston Public Library have been placed on administrative leave pending an internal investigation, a library spokeswoman said Tuesday evening.
The employees were suspended without pay on July 18, the spokeswoman, Lisa Pollack, said in an e-mail. She declined to identify them or discuss the reason they were placed on leave.
Pollack said she was “unable to comment further at this time due to this being a personnel matter.”
The library system’s president, David Leonard, declined to comment and referred inquiries to Pollack.
Laura Oggeri, a spokeswoman for Mayor Martin J. Walsh, deferred comment on the matter to library officials but said Walsh has full confidence in the BPL’s leadership.
Elissa Cadillic, president of AFSCME Local 1526, the union representing library employees, could not immediately be reached on Tuesday evening.
The suspensions, first reported in the Boston Herald, come more than three years after the temporary disappearance of two historic art prints at the library’s main branch in Copley Square brought down its top leaders.
The library’s keeper of special collections, who was responsible for overseeing the rare prints, was suspended after they were found to be missing and then fired quietly in October 2015.
