The 22-year-old tourist sexually abused in Central Parklast week had met her attacker moments earlier — when he offered to demonstrate yoga positions on her, police sources said.

The man struck a conversation with the victim about yoga and exercise inside the park near the 65th Street Transverse and West Drive at 6:30 p.m. and started to demonstrate the moves when he suddenly attacked her, according to police sources.

The suspect, wearing a tank top and trucker hat, was caught on surveillance video casually exiting the park after the attack.

The victim declined medical attention, police said.
