WASHINGTON -- A foreign exchange student is in custody after the sheriff's department says the man sexually assaulted a 17-year-old in Stafford County.
On Saturday, Stafford County Sheriff's Office Deputy Thomas Grasso responded to a Stafford County residence for a possible domestic disturbance. While Grasso was investigating, he learned that 20-year-old Hamad Mastour Alsuwat -- a foreign exchange student living in the residence -- had sexually assaulted a 17-year-old girl who lived there.
Alsuwat was not at the residence when police responded.
Stafford County officials contacted the U.S. Department of Homeland Security in the chance that Alsuwat was a flight risk.
U.S. Customs and Border Protection arrested Alsuwat on Sunday as he was preparing to board a flight out of Washington Dulles International Airport bound for Saudi Arabia.
Alsuwat is charged with object sexual penetration.
Officials have not said where Alsuwat attended school as a foreign exchange student.
