Police have linked a recent sexual assault in Park Slope, Brooklyn to nine similar attacks throughout the borough that have taken place since March.
The latest attack happened Wednesday night at Prospect Avenue and Fourth Avenue in Park Slope.
Investigators say the 20-year-old victim was leaving an R train station when she was grabbed by a man and assaulted.
The nine previous attacks on women between the ages of 21 and 36 took place over more than six months in Park Slope, Sunset Park and Greenwood Heights.
The first assault, which also took place in Park Slope, was caught on surveillance video.
Police believe that more than one man may be behind the attacks.
"It only takes one time to have something horrific happen. So, you can never be too safe. It only takes one time," said one local.
"I walk her when it gets dark. She calls me from the train, I live up the street," said another.
"It be a good idea maybe for the community to form a civilian patrol with the NYPD, letting the NYPD know what's going on," said Benjamin Garcia of the Guardian Angels.
Police have distributed sketches of the suspects, seen above.
The man wanted in Wednesday's attack is described as 5-feet-8-inches tall, and was seen wearing a black hat and a black t-shirt.
Unrelated Attack At Another Subway Station
Meanwhile, investigators are looking into an unrelated attack near the Fort Hamilton subway station.
As of late Thursday, investigators did not believe it was connected to the pattern.
Police said a man caught on surveillance video was armed with a knife when he grabbed a woman by the throat at about 2:30 a.m. Wednesday.
Authorities said he demanded that she remove her underwear, before running off with her pocketbook, iPhone and money.
Police describe the man as being 45 to 50 years old, around 5-feet-10-inches tall, weighing 200 pounds with a stocky build, a bald head and facial hair.
He was last seen wearing a burgundy sweater and dark colored pants.
