Cops release video of creep who touched 4-year-old on subway

Cops on Saturday identified the violent creep who they say touched a 4-year-old girl’s buttocks on a Bronx train, and, when confronted by the girl’s mom, threatened to shoot her.

Kwame Johnson, 42, boarded a southbound No. 4 train around 11:24 p.m. Thursday at Jerome Avenue and West 183rd Street — and approached the girl and her 33-year-old mom seated inside, police said.

Johnson — who was not known to the girl — sat down on her left side and placed his right hand under her buttocks, cops said.

When the child’s mother noticed what was going on, she confronted Johnson — who responded by threatening to shoot her, police said.

The woman and her daughter quickly separated themselves from Johnson, and the mom snapped a picture of him with her cellphone, cops said.

Then Johnson bolted from the train at Grand Central Station.

Video, taken by a witness and also released on Saturday, shows the alleged groper in conversation with a small group.

Cops describe Johnson as a medium-built black man with dreadlocks and a beard. He was last seen wearing green overcoat, gray sweatpants and white sneakers. He remained at large Saturday.
