PHILADELPHIA (CBS) – The social media scandal rocking the Philadelphia Police Department takes center stage on Tuesday at City Hall. City Council is holding a hearing at 1 p.m.

On Monday, Mayor Jim Kenney briefed community leaders on the investigation into offensive posts allegedly involving Philadelphia police officers.

In June, a watchdog group called The Plain View Project discovered the controversial posts of police officers who worked in Philadelphia and in other cities around the country. Some posts were racist, anti-Muslim and even violent.

The researchers identified nearly 330 active-duty Philadelphia police officers.

In July, 13 police officers lost their jobs.

Many more were placed on desk duty and CBS3 is just learning an unknown number of involved officers have resigned.

Today’s hearing is being called by at-large Councilman Derek Green.

“From across Philadelphia people are gonna voice their concerns on this issue. But we’re also going to hear from our acting police commissioner,” Green said.

Philadelphia community leaders say more firings are expected.
