Operation ‘Cold Day' Sting Out of Bay Area Warehouse Nets More Than 100 Arrests

A two-year-long sting operation has netted scores of drugs, weapons and arrests of suspects who allegedly brought contraband to a non-descript Bay Area warehouse run by undercover agents, according to federal officials.

More than 100 suspects were ensnared in “Operation Cold Day.” Many are from Alameda, San Mateo and San Francisco counties, U.S. Attorney Brian Stretch said. Authorities were still making arrests Thursday.

"The objective of Operation Cold Day was very simply to get guns and drugs off the streets of our communities," Stretch said.

Many of the alleged thieves were involved in burglary and auto theft rings in San Francisco and Oakland, sources say. The operation involved law enforcement from San Mateo County, Daly City and San Francisco as well as federal ATF agents.

Investigators, including those from the Department of Alcohol, Tobacco and Firearms, said they were able to interrupt supply chains of narcotics and illegal firearms.

"This Operation Cold Day resulted in the largest number of arrests in ATF history," said Jill Snyder, ATF special agent in charge.

Officials said they targeted home bases for gang members and other invididuals, some of whom played a role in violent crimes, including homicides.
