The Supreme Court says a school's strip search of an Arizona teenage girl accused of having prescription-strength ibuprofen was illegal.

The court ruled on Thursday that school officials violated the law with their search of Savana Redding, who lives in Safford in rural eastern Arizona.

Redding was 13 when officials at Safford Middle School ordered her to remove her clothes and shake out her underwear because they were looking for pills. The district bans prescription and over-the-counter drugs and the school was acting on a tip from another student.
