The Bears released Jeremiah Ratliff last week after the veteran tackle showed up to Halas Hall in no condition to work and got into a heated exchange with GM Ryan Pace.
Sources told CSNChicago.com's John "Moon" Mullin that Pace attempted to dial down the moment, but Ratliff's threatening behavior prompted the team to call the Lake Forest Police Department because they feared for their safety.
On Friday, a report from TMZ Sports showed why exactly the Bears had a reason to be concerned.
According to the report, Ratliff told somebody at Halas Hall that he "felt like killing everybody in the building" before gathering his belongings and leaving the team facility without further incident.
However, Ratliff returned later on that day saying that he needed to retrieve his cell phone from his locker. When escorted into the locker room to retrieve his phone Ratliff told another person "I am the devil" and that he "wished staff member's children would die."
The Bears then ordered Ratliff to leave the property and not return.
Bears director of security John Tarpey then called the police non-emergency number, which TMZ Sports obtained here, for police assistance at Halas Hall because they believed Ratliff owns multiple firearms.
"Since the day of the call, he has not been back to the facility and they have had no further problems," Lake Forest PD Deputy Chief Karl Walldorf told TMZ Sports.
Ratliff has yet to be charged with a crime nor has he signed with another NFL team.
