A Brooklyn man has been arrested for sexually assaulting three women. Federico Chamorro Yax is being charged with assault, sex abuse and forcible touching. Yax is 22-years-old and originally from Guatemala.

The most recent assault took place early Sunday morning in Sunset Park as two women, both 22-years-old, were walking home together.

A man followed them from the subway station and as they neared the apartment they share, the suspect came running from behind and sexually attacked one of the women. Her roommate intervened, tackling the suspect.

The struggle ended up on the ground, at which point the suspect groped the second woman. That victim suffered an arm injury in the ensuing melee, but managed to wound the suspect. He fled, they ran into their home and called police.

Investigators connected the case to another sex attack they were investigating, also in Brooklyn, on September 4th involving a 30-year-old woman. Police have surveillance video of the suspect, and when they arrived at his door, sources say Yax's face was scratched and bruised. Following line-ups on Monday, he was officially charged in connection with those incidents.

The attack on Sunday bore similarities to a high-profile string of sex assaults that has women across Park Slope, Sunset Park, South Slope and Bay Ridge worried, and police frustrated.

Since March, at least 10 such attacks have taken place, and police believe there may be at least two suspects in that particular pattern. The main similarity in the Sunset Park attack is that the two victims were followed home from the subway station and jumped from behind as they got close to their home, but Yax is said to be under 5 feet tall - which does not match the description of the suspect in the other cases.

One law enforcement source tells PIX11 News, copycats have become a concern as the investigation into the Brooklyn pattern continues. Another confides that it's more likely opycats are would strike closer to where the bulk of attacks are taking place, in Park Slope.
