A man has been filmed appearing to try and strangle a woman waiting at a bus stop with a shoelace in a random attack before a “Good Samaritan” stepped in to rescue her.
Aaron Quinones, 27, has been charged with attempted murder after he assaulted the woman he did not appear to know, at a bus stop near Miami International Airport.
Footage shows the unnamed victim, aged 26, who was using her phone and was standing next to luggage when Quinones launched his attack and grabbed her by the neck at around 11am on January 2.
Beforehand he appeared to be crouching down and taking a lace from one of his shoes.
He can be seen forcing her onto a bench and is on top of her with the shoelace as she tries to kick and punch him away.

Then a man wearing a green t-shirt appears and footage shows him pushing Quinones away before the video ends.
The woman was treated at the scene by emergency services and her condition is unknown.
Miami-Dade police officer Angel Rodriguez, reported the Daily Mail, said: "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."

The man who stepped in to help left the scene before police arrived and they have appealed to the public to locate him.
A police statement read: "The Miami-Dade Police Department, Airport District has arrested an individual for attempting to strangle a female at a bus stop.
"According to investigators, the victim was waiting for a bus when the subject approached her from behind and began to strangle her with a shoelace. As the victim attempted to defend herself, the subject beat her repeatedly.

"A Good Samaritan stepped in to stop the attack, and the subject fled on foot. Miami-Dade Fire Rescue responded and treated the victim on scene. Officers patrolling the area located the subject matching the description provided by the dispatcher. The subject was arrested and charged accordingly.
"Officers want to speak to the good samaritan, who was not on the scene when they arrived. Investigators urge anyone that has any information or that may have been victimized by this individual to call the Airport District at (305) 867-7373."
