Portland police say the FBI is looking into credible security threats to PPB officers, who say their employees and their families are facing threats.

Kieran Ramsey, an FBI Special Agent in Charge of the region, wouldn’t confirm or deny any specific investigations but says law enforcement has been subject to an increased threat level recently, KOIN reports.

Threats against PPB officers come after several officer-involved shootings. PPB also says suspects have hurt and even seriously injured officers, which have sent some officers to the hospital.

“If you look at even recently, in the metro area, there were a number of instances with officers being assaulted,” Ramsey said. “I think it’s by the grace of God that we’re not attending a police funeral.”
