FINDLAY TOWNSHIP, Pa. -- Police in Findlay Township said three teens were arrested Thursday on suspicion of taking part in the Route 60 balloon pranks.

Last week, balloons filled with ketchup, mustard and honey were dropped from an overpass onto traffic, WTAE Channel 4 Action News reported.

Investigators said they have surveillance tape of one of the alleged suspects buying the ingredients.

Police said the teens said they were not copying the Parkway West rock thrower.

The teens said they did it because it was "something to do," according to police.
