Federal Way police arrested a 34-year-old man late Sunday after a standoff at Park at Dashpoint apartments.
Officers were called about midnight to the complex at 31736 50th Lane SW after a woman reported a man threatened her with a handgun after an argument over money.
The woman fled the apartment and called 911.
The man who allegedly threatened her refused to come out of the apartment or answer his phone, police spokeswoman Cathy Schrock said Monday.
After police obtained a warrant about 3:15 a.m., the man surrendered and was taken into custody on suspicion of felony harassment and being a felon in possession of a firearm.
Details of the argument were not immediately clear.
