Replying to Mugged for candy

so my friend and i are sitting outside giving out candy to young children when a few guys from my school(sophmores) drop buy and grab a bunch of candy, not a prob. cause we have tons. but then a car pulls up slowly besides them while theyre walking down my drive way (which is connected in two parts) and three guys in superman costumes (full on spandex) jump out and mug...punches and everything...them taking theyre candy. the supermen jump back into theyre car and circle a few times around my driveway going pretty fast, got a call just a few min. ago apparently those same guys are egging trick or treaters across town
