(CNN) -- Three American college students detained in Cairo since Monday night were released from police custody Friday and were headed to the airport to return to the United States, an attorney for one of the men said. 

The men will board three separate commercial flights to return home, according to Joy Sweeney, the mother of Derrik Sweeney. 

Theodore Simon, an attorney for the family of Gregory Porter, told CNN that "his parents anxiously await his return." 

The three -- Porter, Sweeney and Luke Gates -- were arrested after being accused of throwing Molotov cocktails in the unrest that has rattled the country since last week. Their release was ordered Thursday. 

Joy Sweeney said earlier Friday that the paperwork to release the men had been completed. Derrik Sweeney's father, Kevin Sweeney, told CNN his flight is scheduled to leave Cairo at 10:30 a.m. Saturday (3:30 a.m. ET) and he will arrive in his home state of Missouri on Saturday night. 

"He's extremely excited," Kevin Sweeney said of his son. The family was planning to hold a belated Thanksgiving meal Sunday. 

Joy Sweeney said her son told her Wednesday in a telephone call that "they had done nothing wrong." All had been attending American University in Cairo on a semester-long, study-abroad program. 

Sweeney, 19, is a Georgetown University student from Jefferson City, Missouri; Porter, 19, is from Glenside, Pennsylvania, and attends Drexel University in Philadelphia; and Gates, 21, of Bloomington, Indiana, goes to Indiana University. 

Adel Saeed, the general prosecutor's spokesman, said Wednesday that a bag filled with empty bottles, a bottle of gasoline, a towel and a camera had been found with the three American students.
