A suspect is in custody after a commercial vehicle crashed into a Texas department of public safety (DPS) office in a rural town west of Houston on Friday, seriously injuring several people, according to the agency.

Officials have also said the crash may have been a deliberate attack carried out by someone who had been denied a commercial driver’s license.

Texas DPS officials said in a social media post on X that the crash happened at the agency’s office in Brenham, Texas, located about 75 miles west of Houston. Officials said there are reports of multiple serious injuries but did not specify how many people were affected or the extent of the injuries. They also requested people avoid the area to clear the way for responding medical personnel.

The Texas rangers are investigating the incident and there is no further threat, DPS officials said on Friday.

A state lawmaker said the vehicle was stolen in an apparent “intentional” crash. The state senator Lois Kolkhorst said three people were airlifted to a hospital and three more were transported in serious condition following the commercial vehicle crash.

In a separate social media post, the Montgomery county government official Mark Keough said the driver responsible for the crash had been rejected for a commercial driver’s license on Thursday. “He returned with intent to harm,” Keough said.

Multiple news outlets showed images of a large, red tractor-trailer hauling material on a flatbed in the parking lot of the building. The front end of the 18-wheeler was damaged and covered with debris from the front doors of the office. Debris was also scattered out front near a gaping hole in the entrance.

DPS officials did not immediately respond to requests for additional information.

City of Brenham officials did not immediately respond to calls seeking further information.
