Potential bombs mailed to Obama, Clintons intercepted by US Secret Service

The incidents follow an earlier discovery when police 'proactively detonated' a pipe-bomb found at a residence owned by billionaire George Soros

Potential explosive devices addressed to the homes of former Presidents Barack Obama and Bill Clinton were detected and intercepted by the US Secret Service, which has launched a criminal investigation into the incidents.  

"The packages were immediately identified during routine mail screening procedures as potential explosive devices and were appropriately handled as such," the Secret Service said in an emailed statement Wednesday. "The protectees did not receive the packages nor were they at risk of receiving them." 

One device was sent to the home of Bill and Hillary Clinton in Chappaqua, a suburb about 40 miles north of New York
