RUSSIAN IMMIGRANT BUSTED AS BOMBER!

Investigators fear he's Kremlin mole ordered to sow chaos in America

A SUSPECTED Russian spy was nabbed in Philadelphia with enough bombmaking material to level a city block - and he could be just one of hundreds of strongman Vladimir Putin's goons burrowed deep in the American homeland, warn sources.

Russian immigrant Evgenii Sadrislamov, 28, reportedly squirreled away more than 50 pounds of explosives as well as homemade explosive devices and "extensive literature" on bomb-making inside a laboratory in the basement and garage of the otherwise nondescript rowhouse where he lived.

"We really escaped a major tragedy on this one," declares Deputy Police Commissioner James Kelly III.

Cops found the stash of explosives after plumes of smoke were seen billowing from the house.

Stunned neighbor Gerald Brady says, "I would never imagine somebody that lives on my block a couple doors down would be doing something of that nature."
