New York City police have arrested at least six people over violent threats to police since the deadly shootings of two officers last weekend.
According to Reuters, "two men were arrested for threatening New York police on Thursday, including one who called the precinct headquarters of two officers killed as they sat in their patrol car and asked to speak to one of them."
Tyrone Melville was arrested on Wednesday after he allegedly called the switchboard of Brooklyn's 84th Precinct, where the slain officers were based, police spokesman Sgt. Carlos Nieves told Reuters. Jose Maldonado was charged with making terroristic threats after allegedly threatening on his Facebook page to kill police officers and posting pictures of weapons
The NYPD had already made four arrests for threats against police officers after combing through "hundreds of online postings" since officers Rafael Ramos and Wenjian Liu were shot and killed on Saturday by a gunman reportedly seeking revenge for unarmed black men killed by police.
On Tuesday, the 75th and 104th precincts in Queens received bomb threats, according to CBS New York. Both buildings were swept by the bomb squad and cleared.
The Sergeants Benevolent Association, one of the largest police unions in the city, tweeted late Tuesday night that the threat came from a confidential informant who said a Baltimore street gang called the Black Guerilla Family "planned to storm the precincts for a shootout with police."
Police have increased security at some station houses, while Benevolent Association president Patrick Lynch in an email reminded members that they are "potential targets" and urged them to always wear their bullet-proof vests and carry a backup gun.
"Cowardly threats of violence against the brave men and women of our police force will not be tolerated," Mayor Bill de Blasio said in a statement on Wednesday. "New York City stands with our police officers in this time of tragedy, as we do every day, and our city will not be intimidated by those spouting hateful, violent messages. We will protect the men and women who protect us."
