A felony criminal mischief charge has been filed against two New Caney men over a fiery pipeline explosion.
Authorities say Sunday's blast in New Caney, about 30 miles northeast of Houston, caused hundreds of thousands of dollars in damage.
The accident involved the release of highly flammable propylene gas.
Nobody was hurt, but at least 250 people had to be evacuated for several hours.
Officers Tuesday arrested 30-year-old Douglas Lloyd Crosby and 21-year-old Dennis Wade Durrenberger Junior.
Montgomery County Fire Marshal Jimmy Williams earlier said evidence shows a trackhoe and bucket truck were tampered with and caused the explosion.
Investigators are looking into whether Sunday's incident is linked to earlier vandalism at other construction sites.
