Fairfield police, at the request of Baltimore authorities, ask the public to be aware of what they call a "partnership" between gangs to "take-out" law-enforcement officers nationwide.

The threat, which Baltimore police call "credible," has apparently taken shape in the wake of unrest in the Maryland city following the death of Freddie Gray, a 25-year-old black man who suffered severe injuries and died last week after being taken into police custody.

Protests over Gray's death have taken place in Baltimore over the last several days, including confrontations with police Monday following the funeral service for Gray.

The Baltimore Police Department's Criminal Intelligence Unit, according to their press release distributed by Fairfield police, has learned that "members of various gangs, including the Black Guerilla Family, Bloods and Crips have entered into a partnership to `take-out' law enforcement officers."

Law-enforcement agencies should take appropriate precautions to ensure the safety of their officers, the Baltimore statement says.

Fairfield police sent the warning to local media outlets at the request of Baltimore authorities, which is asking the information be distributed to "the public and law enforcement nationwide."

Police ask that suspicious activities be reported to local departments.
