US authorities believe that several packages containing pipe bombs sent earlier to the prominent US politicians were processed in a mail distribution center in Opa-locka, Florida, Sputnik reported citing CNN.
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.
At least ten potentially harmful devices and pipe bombs have been mailed to prominent democratic politicians including former President Barack Obama and former Secretary of State Hillary Clinton this week and federal agencies are hunting for the perpetrators. The CNN news agency also was targeted. None of the the devices exploded or resulted in any physical damage or injuries.
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.
