The Georgetown University student arrested during protests in Cairo this week remains in custody, but he was allowed to call his family in Jefferson City, Missouri.
Derrik Sweeney, 19, told his father Wednesday morning that he's being treated well under the circumstances, the Associated Press reported.
He also reportedly told his dad that he was watching the demonstrations but did not throw anything.
Sweeney and two other American students were taken into custody Monday night. Egyptian authorities said they were tossing firebombs at security forces that have been fighting with protesters in Tahrir Square since Saturday.
The protesters are demanding that the current military rulers immediately transfer power to a civilian authority.
