Three men were arrested in Pioneer Square on Tuesday after Seattle police served warrants on a vehicle and three tents and found narcotics, cash and a firearm.

The warrants were served near the intersection of South Main Street and Second Avenue Extension South in downtown Seattle as part of a drug-dealing investigation, police said.

In addition to a loaded revolver, officers seized a switchblade, a pellet gun, more than $1,200 cash, about 139.2 grams of methamphetamine, 6.8 grams of crack cocaine, 3.7 grams of heroin and several oxycodone pills, police said in a blotter post.

Seattle City Councilmember Andrew Lewis — whose district includes Pioneer Square and who is chair of the Select Committee on Homelessness Strategies and Investments — said in an email Wednesday he supports the police action.

“For months, this drug trafficking operation has been a hazard for outreach workers and Pioneer Square residents,” Lewis wrote. “These tents weren’t being used for shelter, they were being used to further an ongoing criminal enterprise. With this threat gone we can now continue our work to get more of our neighbors experiencing homelessness into housing and out of the cold.”

The three men, aged 53, 34 and 32, were arrested for the possession, sale and delivery of illegal narcotics, police said. The 53-year-old was additionally arrested for illegal possession of a firearm.

All three were booked into the King County Jail.
