Today would not be a good day to be driving a Penske truck around Boston

UPDATE: Truck found, it was up to good - legit picking up charity donations - the Globe reports.

Boston and State Police are on alert this morning, in search of an 18-foot Penske truck spotted with blue, plastic 55-gallon drums last night on Columbus Avenue near Mass. Ave.

The Globe reports police issued an alert after receiving a report of "three men loading large buckets of unknown material."

That report came in around 10 p.m. Around midnight, an officer stopped a Penske truck at Stuart and Tremont streets. After it checked out OK, Boston Police notified police between there and Winchester - where it was headed - that it was legit.
