According to the New York Post, the group who carried out the act, fled the scene after robbing the woman’s walker, $22 and credit cards. The elderly victim was rushed to Harlem Hospital soon after. Cops cited that she is on the road to recovery. Not much has been disclosed about the victim’s family background.

The disturbing clip shows three women and one man engaging in a series of attacks, which entailed punching the elderly woman repeatedly, and stomping on her as she lay on the ground. One of the attackers allegedly struck the disabled woman with a cooking pot as well.

While an investigation has been launched into the incident, the NYPD has not made any arrests as yet.

Felonies in subways are on the rise in the city, and another similar incident of a heinous attack was reported over the weekend. As per the police, a woman and her son were unfortunate victims of an attempted mugging attack on their way to her doctor’s clinic on Saturday. The duo -- Than Htwe, 58, and her son, Kyaw Zaw Hein, 22, were allegedly attacked from behind in the Q train station at Broadway and Canal Street at about 9:40 am.

Both mom and son sustained serious injuries and were hospitalized after plunging down a flight of subway stairs post the attack. The distraught family alleged that the woman might never gain consciousness again as all her organs had failed, after the appalling incident. She underwent brain surgery at Bellevue Hospital. A GoFundMe page was set up for Htwe, who’s currently intubated.
