A 34 year-old male construction worker was washing windows on a refurbished home in the 12000 block of Dandelion Way.
One of the suspects, armed with a handgun, jumped over the fence into the yard and demanded money from the construction worker.
The construction worker told him he didn't have any money.
The suspect then patted the victim down and took his keys, knife and cell phone.
The suspect jumped back over the fence and fled with a possible accomplice.
The two got into a late 90's silver Taurus with two additional men already in the vehicle.
Police spotted a matching vehicle on Highway 18 in Apple Valley and made a felony traffic stop.
The suspects surrendered with no resistance.
The alleged gunman is identified as Dejon Walker, 19, of Apple Valley. A second suspect is identified as Miguel Lopez, 22, of Apple Valley.
Two other suspects, ages 16 and 17, were not identified because of their age.
Police say Dejon Walker has been positively identified in a similar armed robbery the night before in the Eagle Rock area.
