A teacher employed at the school attended by the daughters of US President Barack Obama has been taken into custody.
Robert Peterson was slapped with child sex abuse charges after he allegedly showed pornography to a 14-year-old pupil.
The 65-year-old was also claimed to have "inappropriately touched" the teenager.
"This is a shock to everyone - and I'm sure that includes the White House," the Daily Star quoted his lawyer Barry Helfand as saying.
The president's daughters Malia, 11, and Sasha, eight, go to Sidwell Friends School in Silver Springs, Maryland.
