The FBI and a Miami-Dade county police bomb squad are investigating a US postal facility in Florida as part of the investigation into the wave of suspicious packages sent to prominent Democrats and CNN, the police said in a statement.
"Our Bomb Squad & K-9 Unit are currently providing assistance to our federal partners at the @USPS Opa-Locka mail facility as part of the ongoing investigation into suspicious packages located in other jurisdictions," the Miami-Dade police department said in a tweet on Thursday.
Right now, we are at the mailing facility in Opa-Locka where we just saw a K-9 unit go inside. A senior law enforcement official tells us some of the packages with pipe bombs may have gone through this facility. That source says Miami dade police are here for a sweep. @CBSMiamipic.twitter.com/Fpi0LFSbLk

However, The US Department of Homeland Security (DHS) has bolstered security at federal facilities. DHS Secretary Kirstjen Nielsen said that DHS and the US Secret Service are working closely with the Federal Bureau of Investigation (FBI) as well as state and local law enforcement on the active investigation.

Nielsen condemned the incidents in the strongest way possible, calling them "cowardly acts."
US authorities discovered three more suspicious packages on Thursday, two of which were delivered to former Vice Pressident Joe Biden and one that was sent to actor Robert De Niro, a frequent critic of President Donald Trump.
