(CNN) - A man who allegedly attacked two others last month because he perceived them as gay has been arrested.
Alfonso Lanier, 23, was charged Tuesday with aggravated harassment and assault as a hate crime, the New York Police Department said.
Authorities are still looking for a second suspect.
The assault took place August 14 in the Chelsea neighborhood of Manhattan. The attackers used derogatory words about the victims' sexual orientations, New York Police Detective Marc Nell said.
