Bennington police say the group ran 470 feet of extension cord across a four-lane road and through a Home Depot parking lot to power an electric drill used to detach the logo sign early Sunday.
Sgt. Camillo Grande says they also brought a hacksaw to remove the pepper sign, valued at $8,000.
An alarm went off at about 4:30 a.m., thwarting their plans to make their getaway in an SUV.
The four - two college students, a recent graduate and one who is "between work and school" - were cited for grand larceny.
