Attorney Brittney Horstman's bra triggered a metal detector at Miami Federal Detention Center, and security guards would not let her enter, The Miami Herald reported Saturday.
Horstman stepped into a bathroom, removed the bra, and in blouse and jacket cleared the walk-through detector, the newspaper said.
But security guards still refused to allow her in, saying since she was braless she violated prison dress code guidelines.
"So, simply because I was a woman who wore a specific bra, my client was denied access to his attorney today," Horstman said. "This is completely unacceptable."
Attorneys and the prison reached an agreement several years ago allowing female attorneys entry if guards confirmed by using a wand that an underwire bra was setting of the walk-through detector, the Herald said.
Prison officials would not comment on the incident with Horstman, but people familiar with the procedure say the guards on duty Friday probably "didn't get the memo."
