Air and Marine Operations and Customs and Border Protection agents stopped a boat Wednesday off the coast of Sunset Cliffs with 17 men trying to cross illegally into the United States. 16 Mexicans and one Cuban, CBP reports.

"It took two warning shots before the boat stopped," details Tim Sutherland, director of the San Diego Air and Marine Division.

On the night of Tuesday the 15th, a multi-function plane detected the crew off the coast of San Diego with many people suspiciously on board. At 1:30 a.m. they intercepted the crew and fired two warning shots.

After the arrest, they were detained and taken to the dock while receiving medical attention. It is estimated that the age of the detainees was between 19 and 40 years old.

The department details that if anyone has information about maritime smuggling or suspicious activity they should call the Joint Port Operations Center at 1-800-854-9834, ext. 1, or 911.

"U.S. Customs and Border Protection is the unified border agency within the Department of Homeland Security charged with the administration, control, and protection of our nation's borders at and between official ports of entry," adds CBP and Air and Marine Operations.
