The slashings happened around 7:30 p.m. in Astoria Park near the swimming pool.
When officers arrived at the scene, they discovered a 19-year-old man and a 17-year-old girl both with a slash wound to the stomach.
The 19-year-old was taken to Elmhurst Hospital and the 17-year-old was taken to Harlem Hospital. Both are expected to be OK.
Police say the suspects are described as a group of teens.
They say it appeared there was a dispute before slashings occurred, but it's not clear what the dispute was about.
No arrests have been made, and the investigation remains ongoing.
