FAIRFIELD (CBS13) – The standoff scene on Shenandoah Court has been cleared after six people were detained from a house, according to Fairfield police.

Police said they received a call for assistance from the U.S. Secret Service and U.S. Marshal’s Service Wednesday morning after Secret Service agents encountered an “uncooperative person” in a house who barricaded himself and refused to come out.

CBS13 has learned the U.S. Marshals and Secret Service were conducting separate investigations that led both agencies to the same house on Shenandoah Court.

The U.S. Marshal’s Service said they were looking for a homicide suspect wanted for a crime out of the Bay Area, but did not apprehend that suspect Wednesday. A Secret Service spokesperson said, “As a matter of policy we cannot comment on on-going investigations.”

After police established a perimeter, the SWAT team came to the scene with crisis negotiators, who were unable to establish contact with anyone inside the home.

Officials then deployed tear gas inside the house and six people came out. Police said those six people were turned over to the federal agents who were conducting the initial investigation.

The Marshals Office said four of the six people arrested Wednesday had outstanding warrants for other crimes. The two others were “probable cause arrests.”

No injuries were reported in this incident. The scene was turned back over to the federal agents after 3:15 p.m.

Some businesses on Oliver Road, which back up to the residential area, were placed on lockdown during the standoff.
