Three people were robbed at gunpoint while relaxing in Brooklyn’s Prospect Park, police said Sunday.

Two women, ages 20 and 21, and a 20-year-old man were “just chilling” in a field in Prospect Park near 3rd Street in Park Slope at about 1:30 a.m. when two men walked up to them, police and sources said.

One of the men pulled out a handgun and demanded their wallets and cell phones.

The frightened park-goers handed over their property and the thieves ran off, cops said.

No arrests have been made
