Surrounded by a warehouse in San Diego was a sophisticated tunnel used to transport drugs from Mexico to the U.S: Authorities believe the tunnel was recently constructed.

The drug tunnel was shut down by U.S officials on Wednesday night after it was discovered that the tunnel connected the U.S and Mexico borders. Authorities did not confirm how they knew the tunnel was recently completed.

Border Patrol Agents surrounded the respective warehouse where the tunnel was made to carry out the shut-down. This is however not an isolated incident as officials estimate that there are dozens of tunnels designated to smuggling marijuana into the United States from neighboring Mexico.
