Police are investigating new threats against the NYPD since the execution-style murders of two officers in Brooklyn.
As New York's finest mourn the death of officers Rafael Ramos and Wenjian Liu, there is extra security at two Brooklyn precincts.
According to the Daily News, an informant told the NYPD that the prison gang Black Guerrilla Family may be targeting the 79th and 81st precincts.
This is one of at least 40 threats being investigated.
