The four suspects -- two men and two women -- have not been identified, but police believe they were behind a May 6 robbery in Bremerton and a February robbery in the city's Anderson Cove area.
On May 6, residents on 10th Street called 911 after seeing several people running and screaming in the street wearing only underwear. Police soon learned that a man armed with a handgun had barged into a home, forced the residents to disrobe and left with their cash and marijuana.
After interviewing the victims, detectives developed information leading them to a home on Charlotte Avenue in Bremerton. On Thursday, police and the Kitsap County SWAT team served a search warrant on the house and arrested a man and a woman. On Friday, police arrested another man and woman in Kent.
Along with the four arrests, detectives recovered cash, stolen electronics, and three stolen firearms: a .22 caliber handgun, a .40 caliber handgun, and an AR-15 automatic rifle. The guns were all stolen from the King and Snohomish County areas.
Police also found evidence that links the foursome to a February home invasion robbery in Anderson Cove.
In both incidents, police say the robbers targeted victims believed to be dealing marijuana.
"While the law on marijuana is changing, the decision by any resident to traffic in drugs results in negative consequences for the neighborhood, and these 'drug rips' are just one example," Bremerton Police Chief Steve Strachan said in a Friday news release.
All four suspects were booked into Kitsap County Jail on suspicion of robbery, trafficking in stolen property and possession of a stolen firearm.
