Colorado Springs police arrested a man in connection with nearly 3 pounds of illegal narcotics that was shipped through the U.S. Postal Service on Thursday.

Employees at a local USPS suspected a package contained narcotics. When the Colorado Springs Police Department and a Fountain K-9 unit arrived on the scene, it was confirmed that the package contained illegal substances, according to the Police Department’s online blotter.

USPS delivered the package, and when the suspect picked it up from the mail, police made contact, seized the narcotics and arrested the suspect.

The man’s identity and the type of narcotic were not immediately released by police.
