Helicopter spraying liquid on people in field

Possible hazard.

RP states that at (number withheld) Roosevelt Ave, he's in the field and that there is a helicopter in the area spraying a liquid in the field and it's getting on people as well as his vehicle.

RP was anonymous.

I only have a 10-21 number for him.

Just wanted to report it because whatever the liquid is, is getting on people at (number withheld) Roosevelt Ave in the field.
