Saturday night’s panic on the Great Lawn turned into what resembled a yard sale at the Central Park police station Sunday as concertgoers who fled the Global Citizen music festival amid a gunfire false alarm returned in search of the cellphones, bags and other belongings they left behind.

Dozens of people lined up outside the station house to retrieve their property, which cops at the typically quiet command spent all Saturday night into Sunday morning sifting through and logging.

“It looked like a flea market,” said one concert worker who helped drop off the items — which included enough keys to fill a 2-foot by 2-foot cardboard box — at the cop shop.

Some were lucky, like 16-year-old Dutch tourist Denise Brakel, who lost her phone when she and her dad, Alexander, fled what they thought was gunfire between sets by Cardi B and Janet Jackson — but turned out to be the clang of a metal barrier falling over.

“I think it is so cool no one stole the phone,” said Alexander. “When I called [Denise’s] cell last night, a police officer picked up and said, ‘We have it, come by the station in the morning.’ ”

Others weren’t so fortunate, including Santiago Patino, 18, whose treasured leather jacket was nowhere to be found.

“The jacket was very special to me,” said the high-schooler, whose global-issues class of 33 kids and their teacher came up from Carrboro, NC, for the annual charity concert.

“Cops have no clothes here,” he said dejectedly.

Two girls sympathetic to the task faced by cops in inventorying the mountain of miscellany came bearing a box of donuts.

But whether or not they recovered their belongings, all were grateful that finding their jackets and cellphones was the biggest worry they had after the incident.

“A lot of people panicked. They thought they were going to die,” said Alexander Brakel.

“We were sitting and saw the whole crowd moving toward us. I grabbed my daughter and ran. Either run or get run over.”

Seven people suffered minor injuries in the pandemonium.
