Two masked men robbed five George Mason University students at gunpoint inside a Fairfax home Tuesday around 11 p.m., Fairfax County police said.

The students were studying, playing video games and chatting when the men entered the home in the 4800 block of Carriage Park Road and began yelling and demanding money and valuables, police said.

After the suspects ran throughout the home, the students complied with the demands and the suspects took electronics and other items, police said.

A police helicopter and a K9 unit responded to the scene minutes after the robbery was reported, but the suspects could not be found, police said.

“Part of the investigation to determine if the suspects had been there before,” said Lucy Caldwell, a spokeswoman for the Fairfax County police. “It is also under investigation if doors of the home were locked.”

The suspects were described as black, wearing dark clothing and about 6 feet tall. They appeared to be around 20-years-old.
