Tex. R. Civ. P. 692
Disobedience of an injunction may be punished by the court or judge, in term time or in vacation, as a contempt. In case of such disobedience, the complainant, his agent or attorney, may file in the court in which such injunction is pending or with the judge in vacation, his affidavit stating what person is guilty of such disobedience and describing the acts constituting the same; and thereupon the court or judge shall cause to be issued an attachment for such person, directed to the sheriff or any constable of any county, and requiring such officer to arrest the person therein named if found within his county and have him before the court or judge at the time and place named in such writ; or said court or judge may issue a show cause order, directing and requiring such person to appear on such date as may be designated and show cause why he should not be adjudged in contempt of court. On return of such attachment or show cause order, the judge shall proceed to hear proof; and if satisfied that such person has disobeyed the injunction, either directly or indirectly, may commit such person to jail without bail until he purges himself of such contempt, in such manner and form as the court or judge may direct.
