Teenagers who were getting a jump on Halloween by dressing up as bushes and surprising people in a Union County park could face arrest.

Officials with the Union County Police Department say that they fear the self-proclaimed "Rahway Bushmen" could cause someone to fall in Rahway River Park, get hurt and sue the county.

Two of the high school students cover camouflage suits with brush while a third acts as lookout. They stand in the park and say "hi" to unsuspecting visitors.

One of the teens, who would not give their names, told NJ.com it's more or less an idea to try to make people smile.

Elisa Rodriguez, who heard funny voices and ruffling of leaves, says it was hilarious and the teens should be applauded.

The town invited the teens to Trunk or Treat on Saturday.
