CHARLOTTE, N.C. -- A street near the University of North Carolina at Charlotte is back open after Charlotte-Mecklenburg police blew up what looked like a pipe bomb.

The bomb squad blew up the device found in a convenience store dumpster around 10 a.m. The clerk at the store at the intersection of University City Boulevard and John Mark Road found the cylinder wrapped in black tape, which was attached to what looked like a timing device.

Investigators now say it was not a real bomb, but they have no idea who put it there or why.
