Seven people were arrested last Thursday when Washington police served a search warrant at a home on East Ninth Street.
The seven were booked on suspicion of drug possession and released pending lab analysis of evidence that was seized, according to Police Chief Ken Hahn.
Hahn said Officer Joe Renkemeyer developed information and obtained a search warrant for the home in the 1700 block of East Ninth.
Sources said that neighbors had been complaining about loud parties and lots of traffic at the home.
There were 12 people at the home when officers served the warrant.
Inside the house, investigators found approximately a quarter-pound of suspected marijuana along with suspected heroin and prescription drugs, Hahn said.
Officers also seized a large amount of drug paraphernalia, according to reports.
Detective Sgt. Jason Grellner, head of the Franklin County Narcotics Enforcement, said the task force assisted in the search.
Grellner said as officers were preparing to serve the warrant they saw a vehicle leaving the area and stopped it.
Four people in the vehicle were questioned. They allegedly had a shotgun and a handgun in the car along with two “large” marijuana cigarettes, Grellner said.
Authorities said six different individuals were living in different areas of the house.
Hahn said the owner of the house is working with law enforcement to remove the tenants.
