Many young people, including Albino's 17-year-old son, dealt with the situation by joining gangs, said Akram Abdo, a gang researcher at the Forced Migration and Refugee Studies department at the American University in Cairo.
With gang membership now estimated in the hundreds, many young Sudanese living in gang-dominated neighbourhoods feel forced to choose between one gang or the other.
"The way it is, you need to choose a gang to be in. If you don't, they might see you in the street and attack you," said Marc.
"I am not an Outlaw," said Albino, "I am a father. But if the other gang knew that my son was an Outlaw, they would attack me, too."
The gangs, whose members are typically in their late teens and early 20s, base their membership not on tribe or religion, but on the Cairo neighbourhoods that they claim to defend, Abdo said.
Community leaders say fellow Sudanese are often the victims of muggings and robberies, which pay for the gangs' lifestyle of expensive clothes and parties.
"A lot of the guys in the gangs have been here for six or seven years, and they don't study or work," said Andria, 24, who said he has friends in both gangs.
"They all just sit around with nothing to do," he said.
WITHOUT A CULTURE
"I tend to think these youth are a people without a culture," said Father Simon, whose Sakakini Church has seen numerous young people absorbed by the gangs.
"On the television, they see these American gangs with baggy trousers and they try to imitate that."
Many gang members left their parents behind in Sudan and came to Egypt expecting to be sent to the United States or Europe, said Richard Allhusen, director of St. Andrews school for refugees.
"The leaders told them 'bring your suitcases because the planes will pick you up here and bring you to America'," he said.
When that prospect evaporated, the resulting frustration had "a ripple effect" in the community, he added.
"The gangs became attractive then, to join, to be part of a group.
"These are poor misguided boys," he added.
"Still, the answer can't be 'all of Sudan let's move to a Western country', it's got to be 'let's find peace at home'."
