A Coast Guard crew on Tuesday found 20 illegal migrants in the waters off the Southern California shores.

The crew of the Cutter Haddock intercepted a 30-foot panga-style vessel 21 miles off Point Loma, the Coast Guard said. 

The boat was spotted by a U.S. Customs and Border Protection Air and Marine Operations patrol aircraft and notified the Coast Guard. A small boat crew on the Haddock rushed to the boat and found the migrants.

“In the last month or so, we’ve had a large increase in the number of pangas that have come up on our beach,” San Clemente Mayor Steve Knoblock previously told Fox News Digital. “It happens, and nobody seems to notice. No one seems to capture it. There’s no interdiction, and we’ve been having them with much greater frequency.” 

“President Trump has done a great job of securing the Mexican border in San Diego, but we’re getting people from 150 countries that are coming up by water,” Knoblock added. “It’s like the land invasion has been stopped, but the sea invasion is starting.”

San Clemente is located on the border of Orange and San Diego counties. The city is considering working with border authorities to install and monitor cameras to focus on the waters off the coastal enclave to spot boats carrying illegal migrants.
