There have been several reports of undocumented immigrants using jet skis to go from the Tijuana River in Mexico to Imperial Beach or Coronado, Calif.

According to Paul Carr of the U.S. Border Patrol, last Friday witnesses saw a jet ski land near Imperial Beach and the rider was seen changing from wet clothes to dry apparel.

From August to September, there have been six cases of undocumented immigrants being taken into custody, but there's no way to know how many slipped by the U.S. Border Patrol, noted

All 16 people arrested since Aug. 27 have been Mexican citizens, but none were arrested while possessing guns.

Carr claims there have been more than 550 of these types of arrests since the start of the 2012-13 fiscal year. However, it’s unknown if the numbers have gone up or down from the previous year.
