Photos obtained by The Post on Wednesday show the gnarly gash that an NYPD transit cop suffered while tussling with an accused turnstile jumper — as the cop-socker was hit with assault charges and an accomplice was also charged.

The image depicts a nasty, roughly 4-inch gash on the back of the unidentified officer’s head, which had to be closed with multiple stitches.

The melee kicked off when Deshawn Daniels, 35, allegedly hopped the turnstile at the East 105th Street station in Canarsie around 12:15 p.m. Tuesday and tussled with officers who tried to stop him, according to cops.

Tiffany Jordan, 31, also entered the fray, cops said.

At one point, one of the transit cops fell and slammed the back of his head on the ground, the NYPD said. It was not immediately clear what led to the fall.

Daniels was charged with two counts of assault on police, resisting arrest, fare evasion and obstruction of governmental administration, according to the NYPD. Jordan is facing charges of resisting, obstruction and disorderly conduct, cops said.

The NYPD and MTA have stepped up patrols in 50 city subway and bus stations to crack down on fare-beating.
