New York (CNN) -- A cashier at a New York fast food restaurant has been charged with felony assault for beating two unruly customers with a metal object during an argument, after cell phone video captured a scene in which one customer climbs across the counter in an apparent attempt to reach the store employee.
The women remain hospitalized in serious condition, police said.
The incident occurred at a McDonald's on West 3rd Street about 12:30 a.m. Wednesday.
The two 24-year-old women entered the store, placed their order and then began arguing with the cashier, 31-year-old Rayon McIntosh, police said.
CNN affiliate WCBS said the altercation began when the cashier questioned a $50 bill the women gave him. They responded by hurling obscenities at him.
A cell phone video shows how the situation quickly escalated.
One of the women curses at the cashier, then reaches over and slaps his face.
The woman then climbs over the counter, sending the cashier running toward the kitchen area. The other woman walks around to join her friend.
The cashier then suddenly reappears with what police described as a metal object and repeatedly hits the women.
Restaurant patrons scream for him to stop, while other employees try to intervene.
The video, one minute and 10 seconds long, shows the cashier hitting the women 10 times as they lay on the floor.
"Stop! Stop!" one woman screams. "Stop it! Call the cops!"
The cashier would pause and begin again every time the women tried to get up.
The two women suffered lacerations to their head and face and were taken to a hospital, police said. One of the women suffered a fractured skull and a broken arm, according to a complaint filed by the Manhattan District Attorney's Office.
Authorities identified them as Denise Darbeau and Rachael Edwards, and charged them with menacing, criminal trespass and disorderly conduct.
McIntosh is currently being held at the Manhattan Detention Complex on $40,000 bail. His next court date is set for October 18.
The franchise owner Carmen Paulino told CNN affiliate WABC that McIntosh no longer works at the restaurant.
"I am extremely disturbed by the events captured on tape and am concerned for those injured," Paulino said. "The actions of this individual are unacceptable and not characteristic of my employees."
McDonald's also released a statement, saying the franchisee is cooperating with the investigation.
"The violence in this video is alarming and reprehensible," it said.
