U.S. Attorney Michael F. Easley Jr. announced today the arrest and unsealing of a criminal complaint against 29-year-old Alexander Justin White, a Durham resident accused of attempting to provide material support to ISIS,

Investigators learned that his flight was set for Dec. 4 from RDU with a return flight to the Triangle on Dec. 18. An FBI special agent noted that White likely purchased a round-trip ticket to avoid arousing suspicion, a common practice among Islamic extremists.

A Durham man was charged by federal authorities with supporting ISIS and later attempting to join the group, according to court documents that were unsealed on Tuesday.
