An elderly New York City man was assaulted in the tony Upper East Side by a stranger who shoved him to the ground, and later appeared to flash a hand signal, just steps from the mayor’s Gracie Mansion, police said. 

The 81-year-old victim appeared to be standing on the sidewalk with a dog and talking to someone holding a baby stroller around 12:30 a.m. on Dec. 25, 2021, when the man approached him, according to video released by the New York Police Department on Wednesday.

The NYPD footage then cuts to the suspect flashing what appears to be the middle finger, though it is unclear if the hand signal was directed toward his victim. 

The octogenarian suffered minor injuries and said he did not need to be taken to the hospital.
