As the officer approached, Rosario shouted at her, "I don't wanna talk to you, I just wanna leave", according to the complaint. Officers left their initial call and came up to their apartment, but the commotion was already over, they said.
Rosario told ABC's NY station, WABC, that her boyfriend and her sister's boyfriend were arguing about a video game when a neighbor alerted police officers to the commotion, which she said was already over by the time the officers arrived. "Next thing I know, he grabbed my arm and pulled me into and crowd of cops".
Ed Mullins, president of the NYPD's sergeants union, has maintained that the officers did nothing wrong, saying, "I can tell you that from what I've seen, I really don't see any issue with using the stun gun".
Rosario was detained by police and released last Saturday after being charged with resisting arrest, second degree harassment, and disorderly conduct.
The NYPD loosened internal restrictions on stun guns in 2016 after a year of training approximately 4,000 officers on how to use the devices, putting the total number of those trained with stun guns in the department at around 10,000.
The incident occurred February 10 as officers investigated a disturbance in a Bronx apartment building.
The man seen holding the stun gun after it was deployed is a plainclothes police officer, WABC reported.
A doctor reportedly assured Rosario that her unborn child, who is 14 weeks along, was unharmed by the Taser's electric shock. And she says she is terrified how the incident will affect her child.
"(There were) more than enough cops to handle me", Rosario told ABC 7.
Both parties seem to agree that the officers originally responded to a complaint about a fight between Rosario's boyfriend and her sister's boyfriend, which Rosario said was over a video game. It was unclear if she had retained an attorney.
The NYPD had no further comment other than to say the video and incident are under review. The video was posted to YouTube by Photography is Not a Crime, an account that describes itself as "one of the leading independent news journals covering civil rights in the United States".
