NEW YORK (CBSNewYork) --Police are looking for a group of teens who have terrorized a Brooklyn neighborhood.
As CBS2's Valerie Castro exclusively reported Thursday night, surveillance video shows a group of teenage boys and girls working together to attack an unsuspecting woman walking alone.
A woman was targeted and attacked under the darkness of a tree on a Bushwick sidewalk.
Police sources said it was a group of teens who terrorized their victim, and threatened her with a gun.
"It's disgusting, simply disgusting," Evett Villafane said.
Her network of surveillance cameras caught the mugging on Sept. 5 around 11:30 at night on Evergreen Avenue.
The video shows a group of what appears to be teenagers, some walking, others riding bikes and scooters, make their way up the street.
Another angle shows the teens hiding behind a white van. On the sidewalk, a young woman walks by alone, carrying a bag and looking down at her phone.
"They waited for her and they mugged her," Villafane said.
Police sources said the 26-year-old victim was pushed to the ground, kicked, and punched.
One attacker pulled out a gun and pointed it at her while the others took her cell phone and wallet with credit cards and cash.
The video shows the suspects leaving, and the victim looking for help.
Villafane heard the commotion and called the police.
"She was scared. She was scared, she was shaking, I felt sorry for her," she said.
The victim was so scared that she's since posted a letter in her building warning neighbors of the violent sneak attack.
In it she wrote, "They threatened to shoot me even after I willingly told them to take everything I had on me, and just please not hurt me."
"They obviously waited for an easy target," Villafane said.
She's also sure someone will recognize the teens.
"As a mother you know the way your child walks, you know their attitude, you know what they were wearing that day, so I'm hoping that someone sees them," she said.
In her note the victim urged neighbors to be aware of their surroundings, not walk alone at night, and to put their safety first.
Police have been looking into whether the group of teens is responsible for other crimes in the area.
