Seventeen trucks were burned this morning at a truck stop on the south side of Indianapolis and fire investigators believe it was on purpose. M&K Truck Centers is now offering a $30,000 reward for info that leads to the arsonist's arrest, in addition to the $1,000 offered by Crimestoppers.

Indianapolis Fire Dept. Battalion Chief Rita Reith said the first call came in around 4:30. By the time firefighters got there, several trucks were already on fire.

"They ad a little bit of difficulty getting back to it because the area was so secure. They had to cut through a couple fences and then do some pretty extensive hose lays for water supply," she said.

It took about 45 minutes to get the fire under control. The fire involved hundreds of gallons of diesel, which spilled during the explosions that resulted from the fire.

"Investigators are saying it was intentionally set and they're looking for one or more persons that they think are involved in setting the fire," said Reith.

She said those investigators do not believe the truck fire is connected to the intentional burning of several vacant houses on the north side, but did say the night of arson fires taxed the resources of firefighters.

"Last night was a little unusual because they were relatively close and in quick succession."

M&K said the company is glad no one was hurt in the fire.

“We are grateful...for the rapid response of the fire department. M&K Truck Centers and our customers have suffered significant loss of property including 12 commercial vehicles that are a total loss and 7 others that sustained significant damage. We are working with the authorities to find the people responsible for this crime. In addition to the Crime Stoppers reward M&K Truck Centers is offering a $30,000 reward for information leading to the arrest and conviction of those responsible for the arson.”
