More than 300 law enforcement agents conducted a massive gun and drug sting operation Wednesday morning, resulting in the arrest of 28 suspects in the greater Washington D.C. area.

The Bureau of Alcohol, Tobacco, and Firearms and Explosives and Federal Bureau of Investigation called the sting Operation Tin Panda, and said it began in the spring.

With the assistance of several local law enforcement agencies, authorities say they began investigating members of the Blood gang and their involvement in violent crime, drugs and guns in Northern Virginia.

Officials said the suspects were wanted for their involvement in a slew of crimes, including homicide, malicious wounding, robbery, shootings, and drug and firearms distribution.

Previous search warrants have landed officials drugs, including cocaine, heroin, crystal methamphetamine, THC and marijuana, and more than five dozen firearms. Wednesday’s operation turned up more guns, heroin and other drugs, authorities said.
