DALLAS (AP) - Two women have sued the Texas Department of Public Safety over a body cavity search by a female trooper captured by patrol car video along a Dallas-area highway.

The lawsuit says the July 13 search of 38-year-old Angel Dobbs and her 24-year-old niece, Ashley Dobbs, was unlawful. The Irving women complained to DPS.

DPS spokeswoman Katherine Cesinger on Tuesday declined comment on the lawsuit. Cesinger says results of a Texas Rangers inquiry were sent to the Dallas County district attorney's office. The dispute is expected to reach a grand jury next month.

The women say a male trooper told them he saw them throwing cigarette butts out a car window, questioned them about drugs and summoned a female trooper for a search.

The two women say no drugs were found.
