The family was sleeping at their home in the 4600 block of South Orcas Street about 3:45 a.m. when they were awaken by the sound of people forcing their way through the back door, according to Seattle police reports.
The intruders demanded money from the family, which included two men, two women and a young child, reports say.
One of the robbers pulled a knife and stole a gold chain from one of the men living at the home. One of the women ran to grab a knife from the kitchen, but another robber met her carrying a gun, according to reports.
The intruders ransacked the home and took off, at which point the family called 911. None were injured.
Police officers and a police dog were unable to find the suspects in the area. The family could only describe them as men in their 20s, between 5-foot-7- and 5-foot-8-inches tall, wearing dark-colored hooded sweatshirts.
Officers searched the neighborhood and called for a K-9 unit, but police were unable to find the suspects, who were described by the victims only as black males in their 20s, between 5'7 and 5'8, wearing dark-colored hooded sweatshirts.
Police ask anyone with information to contact detectives at 206-684-5535.
