Sumner police cordoned off an automotive shop on Main Street East this morning to investigate possible manufacturing of methamphetamine inside.
City of Sumner spokeswoman Carmen Palmer said three people have been detained and police are waiting for a signed search warrant before they go inside.
Palmer said a patrol officer saw suspicious activity in the business located in the 15500 block of Main Street East about 3 a.m. He also smelled the odor of ammonia and saw plastic tubing which are consistent with making meth, she said.
One of the men arrested apparently worked in the shop, Palmer said, adding that the owners of the business who knew nothing about what was going on in the shop at night are cooperating with police.
The Pierce County Clandestine Laboratory Team which handles meth labs was called, Palmer said.
Further details will be posted as they become available.
