One person is now locked up in Fort Worth where arson investigators were called out because of a rash of suspicious fires overnight.
Beginning Thursday night and continuing for eight hours, there were five fires in a one-mile radius near Hemphill Street in the area around I-35W and Biddison.
A Fort Worth Fire Department spokesman says the fires included two cars, an RV, a commercial building and a dumpster.
Investigators are not saying why they think the suspect did it.
