Huh? What happened

[jTheUmp]

Technical foul of some sort.

Hard to say for sure, but my guess is that it was an administrative technical: adding a player to the scorebook or somesuch. Probably was noticed by the table after the official reported the foul and the scorekeeper couldn't find the fouler in the book.

Assuming it was discovered while the ball was live for the first FT attempt, I've have handled it the same way. Talk to both coaches (quietly), clear the lane, administer the remaining free throws, get the game going again (throw-in should be opposite table, but in some tight-quarters gyms I've worked 7th grade games in, I'd administer tableside for lack of space opposite). I would've at least made a T signal to the table though.
