BROOKLYN - Police have arrested a man who allegedly attacked a woman in Sunset Park on Monday.

According to authorities, 26-year-old Adolfo Martinez groped an 18-year-old as she left the 36th Street train station. He is being charged with sex abuse and forcible touching, but cops say he's not connected to the string of sexual assaults that have plagued the borough.

Police say they're still looking for suspects in the other cases and have a new sketch of a man they believe could be responsible. He is described as a Hispanic male, possibly in his early 20s, with a medium build, black hair and a mole on the left side of his neck. Police say they're canvassing several local neighborhoods, passing out fliers and asking local residents if the sketch looks familiar. Anyone with information on the attacks is urged to call Crime Stoppers at 1-800-577-TIPS.
