(CNN) Ten people were detained on Thursday after a small panga boat landed in Laguna Beach, California, according to police.

Nine of them were undocumented immigrants, according to border patrol spokesman Theron Francisco, and the tenth was a US citizen who was arrested for alien smuggling.

Of the nine undocumented migrants, three were Chinese nationals and six were Mexican nationals, Francisco said.

Authorities previously said nine were detained, two of whom were drivers in what police described as "take-away" vehicles waiting to pick the migrants up.

A panga is a boat often used for working off the coast of Mexico or Central America, according to the US Coast Guard . The engine-powered vessels are typically 25 to 45 feet long.
