Surveillance video captures the moment a Good Samaritan intervenes during a vicious strangling attack

A male suspect brutally attacked a woman at a Miami bus stop on Sunday before a Good Samaritan intervened and stopped the beating.

Authorities arrested 27-year-old Aaron Quinones and charged him with felony attempted murder in connection with the attack.

What are the details?

In video footage obtained by the Daily Mail, a male suspect can be seen approaching a woman from behind and placing what appears to be a shoelace around her throat in an apparent attempt to strangle her.

The suspect began garroting the unnamed victim with the shoelace, despite her attempts to fight him off.

When she broke away, the suspect then knocked the woman down to the ground, where he began to repeatedly punch her in the face.

The female victim during the attack began lashing out with her fists and feet in an attempt to stave off the suspect's blows, but by this time, an unidentified passerby ran toward the two with outstretched arms to stop the assault.

At that point, according to the report, the bystander dragged the suspect off of the woman. The suspect then fled on foot, but was found later by police and booked into the Turner Guilford Knight Correctional Center on a $250,000 bond.

The bystander also left the scene before police arrived, and authorities are asking for the public's help in identifying him.

Miami-Dade Police Officer Angel Rodriguez said that the Good Samaritan may well have saved the woman's life.

"Had it not been for a Good Samaritan that stepped in that basically stopped this individual from attacking this victim, the outcome would have been way worse," Rodriguez said.

The outlet reported that the suspect and victim were unknown to each other, and police say that there is no known motive behind the attack at the time of this reporting.
