Investigators say they may be part of a gang that is responsible for other crimes, including robbery of an elderly couple during a home invasion on Labor Day.
Those arrested have been identified as John Wade, 22 and Nassir Cameron, 16, both of West Philadelphia and Keith Morris, 22, of North Philadelphia.
Police say they may be responsible for as many as 10 other home invasions.
It all began after police responded to a home in the 2900 block of Marshall Road in Upper Darby around 3:00 a.m. after getting a 911 call from inside the residence.
Upper Darby Police Superintendent Michael Chitwood told Action News that three suspects, armed with a sawed-off shotgun, entered a home through an open window and terrorized seven people at gunpoint, demanding money.
Police say the suspects made the grandparents, their daughters, and five-year-old granddaughter lay on the floor. One victim described what happened to Action News.
"There was a man coming down the steps with a gun in his hand. He walked over to me and my daughter, who was sleeping, and put a gun up to my head and said 'Don't look at me.' Then he said, 'Where's your money?' Then he took my money and ran back upstairs and put a gun to my sisters' heads."
One of those sisters ran downstairs and called police. So did another resident who was just getting home from work and saw what was happening and fled to a neighbor's house.
Police arrived to find some of the bandits trying to haul away a large screen TV. Two males, one who is just 16 years old, were arrested. A third suspect remains at large.
Police are convinced they are the same home invaders who terrorized an elderly couple in their Drexel Hill home on Labor Day.
"Upper Darby police officers hit a home run today," Chitwood said during a morning news conference. "We feel that these guys are responsible for numerous armed home invasions, certainly the two we have here and in Drexel Hill and certainly others."
"One of these bums is 16 years old, another is 22," Chitwood added.
The home invasion in Drexel Hill happened around 2:15 a.m. on Labor Day. Police say four males broke into a home, located on Kirks Lane, and ransacked the place looking for a large amount of cash they believed was kept there.
They terrorized the elderly residents, an 88-year-old man and a 77-year-old woman by keeping them in their bed at gun and knifepoint.
"At one point one of the invaders comes in with a butcher knife and starts stabbing the mattress and telling them that if they don't tell them where the money is the next stab wound is going in his chest," said Chitwood.
Fortunately the elderly couple suffered no physical injuries.
The bandits eventually made off with two flat screen TV's, a laptop computer, jewelry and the woman's 2000 BMW.
Philadelphia police recovered the stolen car Monday in Northeast Philadelphia after it was involved in a hit and run accident.
As this investigation continues, anyone with information is urged to call police at 610-734-7677.
