Police investigate suspicious liquid left at Muckleshoot building

AUBURN, Wash. -- Police are investigating a suspicious substance left by a man at the Muckleshoot Administration building Tuesday afternoon.

The man had been in the building two days ago to complain about a meth lab that was on his property, according to Sgt. Cindi West with the King County Sheriff's Office.

Then on Tuesday, the main returned again and said something to the effect of, "this is what you get for not listening to me," West said.
 
The man then reportedly dropped a pint-sized Ziploc bag filled with liquid with something taped to it.

The man left but was taken into custody a short distance away along Auburn Way South. The man had a large backpack and that remains at the scene where the man was apprehended.

Meanwhile, investigators are tying to figure out what was in the liquid and in the backpack.
