baltimore protesters

Members of the Baltimore Police Department stand guard outside the department’s Western District police station during a protest for Freddie Gray, Thursday

*Baltimore police say three separate gangs are now working together to “take out” law enforcement officers.

In a statement Monday, the department called it a “credible threat” and said members of the Black Guerilla Family, the Bloods and the Crips have formed an alliance against the police.

The department warned other law enforcement agencies to “take appropriate precautions.”

The police statement came as mourners gathered for the funeral of Freddie Gray, who died of a mysterious spinal injury while in police custody.

Police spokesman Capt. Eric Kowalczyk would not say whether the threat is related to the death of Gray. Kowalczyk said the threat announcement has been circulated to law enforcement agencies nationwide.
