The New York Times’ office on Wednesday was surrounded by large concrete blocks that say “NYPD” on them outside of its headquarters in Manhattan as a part of an enhanced security measure, a spokeswoman for the paper told the Washington Examiner.

The barriers were placed there as “part of our continuing efforts to enhance security at our headquarters building,” said Times spokeswoman Eileen Murphy in an email. She said they were placed there on Wednesday but that they aren’t in response to any new or specific threat.
