Police Not Investigating Kodak Black's NHL Game Grind Sesh, 'They Were Not Having Sex'

Kodak Black isn't in any sort of legal trouble over his NHL game grind sesh ... cops tell TMZ Sports there's no investigation into the matter because "they were not having sex."

The rapper was spotted at the Florida Panthers game on Tuesday enjoying a lapful of butt from his lady friend in a box suite ... and many thought the two were actually getting it on.

Video shot from across the arena showed the couple grinding on each other ... though a more zoomed-in angle of the action seemed to show they were only dancing.

A spokesperson for the Sunrise Police Dept. tells us officers were present in the suite at the time of the action ... and insist the two were not having sex.

"They were just dancing very provocatively," the spokesperson said.

We're told cops asked Kodak and his partner to stop shortly after they began ... and the rapper complied with no issues whatsoever.
