Around 12:30 a.m. Tuesday, flames engulfed the playground.
Officials say an arsonist poured gasoline all over the equipment causing $50,000 to $100,000 in damage.
Fortunately, no one was hurt.
"It's a sick individual. There's no logical reason why someone would do this," Freeholder Bill O'Dea said.
O'Dea says investigators are closely combing surveillance video taken by cameras in and around Lincoln Park hoping they'll find the clue they need to catch who did this.
In the meantime, the playground is fenced off and Amasia Oliver, 4, won't be able to use it.
"I don't want nobody to burn it down," Oliver said. She says it makes her sad that someone burned down her playground.
Amasia's mother Krystal Oliver says she's just happy no one was hurt.
"It could have branched out. There's a tree right there. It could have been much worse than what it was," Krystal Oliver said.
But the sight of charred metal and police tape is unsettling for Amasia, who says she wants to play there again.
When asked what she thinks of when she looks at the burned playground she said, "The bad guys. I don't want the park to go down because I want to play with all my friends."
So far no arrests, as the investigation continues.
