A 91-year-old man was severely injured while walking on the Upper East Side after he was approached by a man who shoved him to the ground and ran away. Police say the unnamed victim was walking on East 86th Street between First and Second Avenues on June 30th at approximately 6:55 p.m. when the assailant "approached him, pushed him to the ground and fled to East 85 Street and First Avenue where he entered a cab and fled the location."

It is unclear what, if anything, motivated the assault. According to the NYPD, the victim broke his right arm in the fall, and also sustained a head injury. ABC 7 reports that he is now forced to use a wheelchair and is "unable to stand because of poor balance. "

Investigators say the suspect is approximately 5"9', 170 lbs with brown hair. He was seen that day wearing a red shirt, white sneakers and blue jeans.
