Sounds like an "unfair act" by a person not subject to the rules and therefore the referee could handle the situation in any way that he feels equitable to include (but not be limited to) treating it as an IW.
Agree 100%. If a player was heading towards paydirt when this occurred, a

could also be awarded. The home management should also be notified to put the

tweeter police

on the prowl. We once had a wild reaction by the band to the ref's whistle back in my daze of a

wide-eyed wingman

.....
(1) Game time 1:30, trip to field 0:45, WH

to pick up our crew @ 12:15;
(2) WH was always

grumpy

on a good day;
(3) WH shows up @ 1:00 ,excuse: "Busy with stuff

";
(4) Crew tries to dress in car - thank

-only 4 man;
(5) Arrive at field @ 1:40 -WH speeds;
(6) Coaches have already held coin toss and teams lined up for kickoff;
(7) We run to our positions and WH

blows RFP whistle;
(8) Band hadn't played Star Spangled Banner and thought it was bandleader's tweet;
(9) Kickoff occurred as band began to

play;
(10) Some players stopped and removed their

helmets, some kept playing;
(11) Runner ran for TD while

WH

REALLY GOT GRUMPY;
(12) All concerned agreed to a "DO OVER"

...
AND THE BAND DIDN'T PLAY ON
THIS OCCURRED IN THE EARLY 1970'S - NO CELL PHONES IN MAINE!!
