SLIDELL, Louisiana (Reuters) -- Two people left a 15-mile-long- trail of doughnuts after they took a Krispy Kreme truck from a parking lot and fled, police said Thursday.

The truck was parked at a convenience store with its rear doors open and engine running while a deliveryman carried doughnuts inside, said Slidell police spokesman Rob Callahan.

Two suspects hopped in the truck and sped off to the nearby town of Lacombe, with doughnuts spilling out along the way, he said.

They abandoned the truck when they were spotted by police responding to reports of a dangerous driver who was losing his doughnuts. Passenger Rose Houk, 31, was captured, but the driver, whose name was not released, ran away.

Houk told police they had been smoking crack cocaine for several hours before the incident, which occurred Wednesday, said Callahan.

Their motive for taking the Krispy Kreme truck was unclear.

"I don't know if it was a need for transportation or if they just had the munchies," he said.
