Philadelphia police said they were aware of social media posts calling for looting and other criminal behavior Wednesday evening.

Police said officers were dispatched to numerous areas of the city due to possible looting.

“Criminal behavior will not be tolerated and our officers are prepared to take any necessary action if warranted,” Philadelphia Police Sgt. Eric Gripp said in a statement. “As Commissioner (Kevin) Bethel stated at Monday morning’s press conference, we will continue to increase patrols and staffing as needed in the coming days to protect our business communities.”

Police said they would monitor social media throughout the evening and share information with partner agencies. They are asking anyone who sees anything suspicious to contact 911.
