LOS ANGELES Travel by bus may not always be the height of pleasantness but it seldom dips to the depths of this air travel indignity.

A Texas woman complained she was forced to remove a nipple ring with pliers to get through security to board a plane.

In the wake of the episode, the Transportation Security Administration says its changing the way its officers search passengers with body piercings.

Mandi Hamlin, 37, had demanded an apology and her Los Angeles-based attorney sent a letter to the TSA requesting a civil rights investigation.

Hamlin was trying to board a flight from Lubbock to Dallas when she was scanned by a TSA agent after passing through a larger metal detector without problems. The female TSA agent used a handheld detector that beeped when it passed in front of Hamlin's chest.

Hamlin said she told the woman she was wearing nipple piercings. The agent then called over her male colleagues, one of whom said she would have to remove the jewelry, Hamlin said.

Hamlin said she could not remove them and asked whether she could instead display her pierced breasts in private to the female agent. But several other male officers told her she could not board her flight until the jewelry was out, she said.

Hamlin was taken behind a curtain and managed to remove one bar-shaped piercing but had trouble with the second, a ring. She said the officer gave her pliers to remove the ring, a process which caused pain.

The TSA said in a statement on its Web site the officers properly followed procedures, but that the procedures must change. In the future passengers can either allow a visual inspection of their piercings, or remove them, the agency said.

The statement stopped short of apologizing to Hamlin.

"TSA acknowledges that our procedures caused difficulty for the passenger involved and regrets the situation in which she found herself," the agency said in its statement. "We appreciate her raising awareness on this issue and we are changing the procedures to ensure that this does not happen again."
