A device — some say was a homemade bomb — exploded just before midnight outside a south Nashville coffee shop.
NewsChannel 5 reports  witnesses said people on the patio at Starbucks on Edmonson Pike were reportedly arguing with people in a car late Tuesday night.
The car left, but returned shortly and threw something on the patio. The device exploded a few minutes later.
No one was injured in the incident, and the Starbucks was open Wednesday morning.
