Seattle police say a home invasion by three men early Sunday morning was motivated by a hunt for drugs.

The incident began early Sunday morning in West Seattle's Roxhill neighborhood when three men, armed with a knife broke in to a home and threatened to kill a 35 year old woman if she did not cooperate.

The Seattle Police Blotter provided details:

"The woman told police someone banged on the back door of her home, in the 7500 block of 32nd Avenue Southwest, shortly after midnight. When she walked back to investigate, a man broke the glass and reached in to unlock the door. The victim headed toward the front door, but one of the suspects barged in, pointed a handgun and ordered her to stop. A second man, armed with a knife from the kitchen, pushed her to the floor and held the blade near her throat.

The robbers told her not to look at their faces, and asked where her safe was. The victim told them it had been stolen several weeks ago. One man held her down at gunpoint while the others ransacked her house. The woman offered them her purse containing $100. The men took the purse and then saw several police cars arriving in front of the house. They fled through the back door.

The victim ran out the front door to alert officers. She was not injured. A neighbor had called the police a few minutes earlier because the men had apparently walked through the yard of a neighboring home. Detectives believe the suspects were looking for illegal drugs. A K-9 team was brought in to help search for the suspects, but no one was found.
