U.S. Border Patrol personnel launched an investigation Friday after a boat arrived at a Southern California beach and 11 people got out and fled, according to a report.

The vessel, described as a 25-foot-long pleasure craft, came ashore at Encinitas, about 25 miles north of San Diego.

The occupants fled through a beach access area and scattered into a neighborhood, Encinitas Lifeguard Capt. Larry Giles told FOX 5 of San Diego.

“They all fled and we don’t have any accountability of the direction where they are,” Giles told the station.
