NAVARRO COUNTY -- A suspect has been arrested after a three-county crime spree forced Interstate 45 to be shut down in Navarro County Tuesday morning.

All lanes of the highway have since reopened.

Officials tell WFAA the unidentified suspect committed a robbery in nearby Limestone County, then an aggravated robbery at a Shell gas station in Freestone County.

The man then stopped his truck on the side of I-45 near Mile Marker 220, and fired shots from a gun.

SWAT officers were called to the scene and surrounded his vehicle.

I-45 was shut down for a short time while the standoff took place.

The armed man was eventually arrested.
