NASHVILLE, Tenn. - An explosive device detonated outside a south Nashville coffee shop just before midnight Tuesday.
Witnesses said nine people were sitting on the patio at the Starbucks on Edmondson Pike.
Some of those people reportedly started arguing with 3 people inside a car.
The car left, but later returned and dropped off some sort of chemical bomb, according to investigators. The device exploded a few minutes later.
Metro's bomb squad was called out to investigate the incident.
Police are looking for a beige or gold four door sedan.
