PHILADELPHIA (AP) — Family and friends of three American students arrested during a protest in Cairo waited anxiously Friday for news that they had been released from police custody.

Derrik Sweeney, Luke Gates and Gregory Porter, who attend the American University in Cairo, were arrested on the roof of a university building near Cairo’s iconic Tahrir Square on Sunday. Officials accused them of throwing firebombs at security forces fighting with protesters.

A court in Egypt ordered the release of the students, a lawyer in Philadelphia confirmed Thursday.

Attorney Theodore Simon, who represents Porter, a 19-year-old student at Drexel University in Philadelphia, said he spoke by phone with Porter, describing the student’s demeanor as “calm and measured, demonstrating a maturity well beyond his 19 years.”

“He was extremely thankful and appreciative for our efforts and the unconditional support of his mother and father,” Simon said.

Porter is from Glenside, Pa., a suburb of Philadelphia.

Sweeney’s mother, Joy Sweeney, said she is “absolutely elated” at the news of her 19-year-old son’s release.

“I can’t wait to give him a huge hug and tell him how much I love him,” she said, adding that the news of the court order was the best Thanksgiving gift.
