BOULDER, Colo. — Police in Boulder County arrested 17 people Thursday in connection with a suspected drug dealing organization.

Some 200 officers from state, local and federal law enforcement agencies executed 10 search warrants on homes in Boulder and Longmont, the Boulder County Drug Task Force announced. Officers seized “significant amounts” of cocaine and meth, as well as cash, guns and vehicles, BCTF said.

The investigation spanned more than 10 months, police said. The alleged criminal organization is thought to have ties to drug trafficking in Arizona, California and Mexico.

“This investigation was brought to a successful conclusion this morning with the arrests of the criminal group’s leaders responsible for importing cocaine and methamphetamines from Mexico to Boulder.” DEA Assistant Special Agent in Charge Keith Weis said. “Colorado’s northern communities are better off today because of this highly coordinated effort.”
