The Philadelphia Police Department has pulled 72 officers off their regular duties as authorities investigate inflammatory social media posts revealed in a database that found thousands of offensive postings by current and former officers, the city’s police commissioner said Wednesday.

Police officials in Philadelphia are describing the action as the largest removal of officers from the street in recent memory.

“We are equally as disgusted by many of the posts that you saw and in many cases, the rest of the nation saw,” said Philadelphia Police Commissioner Richard Ross.

It is the latest fallout since the advocacy group The Plain View Project earlier this month released thousands of Facebook posts and comments by current and former police officers that range from racist memes, to posts celebrating violence and messages containing Islamophobic themes, among other offensive material.

In Philadelphia, Ross said Wednesday that at least “several dozen” of the 72 officers now on desk duty will be disciplined and others will be fired, but he did not provide specifics, including any of the names of those who have been taken off their regular duties.
