FLUSHING, Queens — A transgender woman was slashed by a cat-caller she rejected on a Queens sidewalk and police are searching for her attacker.

The 47-year-old victim was walking along Aske Street near 94th Street about 3:40 a.m. Wednesday when she was approached by a man who asked for a "sexual favor," police said Thursday.

She declined and walked away and that's when the cat-caller slashed her with a box cutter across her stomach and ran away, police said.

The victim was taken to a hospital and underwent surgery for the wound. She is listed in serious condition, police said.

It was the second attack of this kind in the past few months. Late in 2015, a transgender woman was attacked on 93rd Street and Roosevelt Avenue. In that case, a 35-year-old victim was followed home by a man who assaulted her steps away from her front door, leaving her in critical condition.

Police do not believe the attacks are related, but that does little to calm a neighborhood in fear of another assault.

"After dark, these streets become a very dark place," resident Carlos Palomino said.

He said warm summer temperatures often come with rising crime.

"I keep my family off the street," he said.
