We have a report from MSN,

“The captain and first mate of a Mexican fishing vessel are in federal custody after slugging it out at sea with members of the U.S. Coast Guard trying to board their boat.”

The fishing vessel had landed four immigrants and the two boat crewmen were also ashore when border agents arrived on scene. The two crewmen fled to their boat in an attempt to escape. The Coast Guard was called and a vessel dispatched (no indication of type but I surmise something like a response boat medium). The fishing vessel rammed the CG vessel, and the F/V crew resisted arrest.

It is not clear when this happened. Court documents have already been filed and made public. Curiously, I could find no Coast Guard press release on the incident.

Thanks to Joseph L. for bringing this to my attention.
