Jones said state police stopped a Black Acura with Massachusetts plates after receiving a tip from federal authorities that the driver might be armed and dangerous, and possibly carrying a bomb. Jones said the original tip came from a member of the man's family.
"Indications are this was erroneous information, albeit credible-sounding information, and at this point it seems to indicate that this was not a legitimate threat," Jones said.
Authorities initially shut down a 30-mile stretch of the turnpike in both directions from Exit 4 in Mount Laurel to its southern terminus near the Delaware Memorial Bridge. By 8 p.m. part of the road had been reopened, but a stretch between Exit 4 in Mount Laurel to Exit 2 in Woolwich remained closed while a bomb squad checked out the vehicle.
The northbound lanes of the highway were completely reopened by 9:35 p.m. and the southbound lanes by about 10:15 p.m. after the investigators completed their inspection.
Jones said FBI agents were still questioning the man - who was not charged - late Tuesday at the state police station in Moorestown.
