Samuel Rodriguez Reyna, a pretrial detainee confined in the Nueces County, Texas, Jail, awaiting trial on murder charges, appeals the dismissal of his 42 U.S.C. § 1983 civil rights lawsuit challenging his arrest and detention on the grounds that there was no probable cause to arrest him, that the search and seizure of his person was unconstitutional, and that the defendants have conspired to deprive him of his liberty. The district court ordered that the complaint be dismissed pursuant to the abstention doctrine of Younger v. Harris, 401 U.S. 37, 91 S.Ct. 746, 27 L.Ed.2d 669 (1971). It alternatively dismissed the claims for failure to state a claim and as frivolous, pursuant to 28 U.S.C. §§ 1915A and 1915(e)(2), and 42 U.S.C. § 1997e.

On appeal, Reyna renews the merits of his claims and urges that abstention was not warranted under Younger because the murder charges against him were brought in bad faith and with the intent to harass him. He also raises numerous other new assertions regarding the various defendants in his appellate brief. However, he has abandoned by failing to brief any challenge to the district court’s alternative bases for dismissal. See Yohey v. Collins, 985 F.2d 222, 224-25 (5th Cir. 1993). Accordingly, the district court’s judgment is AFFIRMED.
