AUSTIN, Texas — The driver of a stolen semitrailer intentionally rammed it into a Texas public safety office in a rural town west of Houston on Friday, injuring multiple people, according to a state lawmaker.

Three people were airlifted with critical injuries and three others were transported in serious condition after the crash of the commercial vehicle, which was stolen, according to a statement by Texas State Sen. Lois Kolkhorst, who represents the area. Kolkhorst said in the statement that no DPS staff suffered serious injuries and one staffer was trapped “for a period of time” in the building.
