“I was told not even residents were allowed in,” one driver told us, as she sat just a block away from her neighborhood.

“We were actually going to the base, but we can’t get on the base right now. They haven’t confirmed exactly what’s going on,” said Tangie Sands-Miller, who had been in the same spot for an hour.

A source briefed on the incident told CBS4’s Jim DeFede an explosive device became loose and “rolled” into an area where it should not be.
