FBI counterterrorism agents have uncovered a link between Sebastian Gregerson, the American Muslim arrested Sunday after he allegedly bought illegal grenades, and an al-Qaida leader who radicalized underwear bomber Umar Farouk Abdulmutallab, The News learned Friday.

When FBI agents raided Gregerson’s home on the west side of Detroit on Sunday, they found several CDs marked “Anwar al-Awlaki,” the al-Qaida recruiter who met with Abdulmutallab before the failed Christmas Day 2009 terror attack on a Detroit-bound plane, according to sealed search warrant records obtained by The News.

The CDs are listed among dozens of items seized Sunday, including seven rifles, two AK-47 assault rifles, a shotgun, handguns, thousands of rounds of ammunition, computer equipment and cellphones, according to a sealed search warrant inventory.
