He picks up bottles and backpacks and throws them at people experiencing homelessness near the Philadelphia Convention Center.
The video has been viewed thousands of times, leading police to identify the suspect as 27-year-old Naeem Morgan.
"I have never seen anything like that in my life here, it's just really depressing and just really hurtful for us," said Barry Martin, the program director at St. John's Hospice on Race Street. The organization works to find housing and shelter for unhoused people.
"Where is our humanity? Where is the heart that we are supposed to carry with us as we walk around this city?" said Martin.
St. John's has a soup kitchen and feeds 300 men, women and children daily.
Martin says he recently met with city officials in an effort to find a solution to help the growing number of people sleeping in the tunnels near the convention center.
"I just hope they catch him and get him off the street. Let him go sit somewhere and think about it," said a shelter resident, who asked that we not identify him.
Police arrested him at a home in North Philly. He now faces charges relating to simple assault and harassment.
People who saw the video say it's incredibly disturbing.
"You don't know how they got to that point because anybody's life can literally change in a heartbeat like that. It's inhumane," said Jowon Dorbor, of Smyrna, Del.
