Two 15-year-olds - a boy and a girl - and a 12-year-old girl face charges of third-degree assault as a hate crime for allegedly attacking five Asian women from March 31 to Monday, police said.
The victims were between 50 and 71.
The three were arresetd after one of the suspects came forward to police following the release Friday of a security video that showed two girls entering the public housing development where the first alleged attack took place.
Four of the attacks took place in or around the Samuel Gompers Houses and the Baruch Houses - both New York City Housing Authority complexes. The fifth was in or near the Seward Park co-op apartments. Police said two of the suspects lived in the area.
The arrests came the same day that four men were charged with hate crimes in an unrelated case on Staten Island for allegedly beating and robbing a 26-year-old Hispanic man after shouting ethnic slurs.
In that alleged attack, which occurred early Monday morning, police charged three 17-year-olds and a 15-year old with multiple counts of assault, gang assault and robbery, among other charges.
The assailants stole the victim's wallet and cell phone before fleeing, police said.
The suspects were identified as Rolston Hopson, Tyrone Goodman and William Marcano, all of Staten Island. The 15-year-old was not identified because he is a juvenile.
