Police have arrested a man in connection with a series of groping incidents in Brooklyn, including an assault on an 11-year-old girl, officials said.

The man was nabbed after a local resident took a photo of the suspect's ID, Commissioner Ray Kelly said.

"A Good Samaritan chased him [Monday] and then lost him, saw him again [yesterday] and asked him for his identification," Kelly said, according to NY1.

There are at least four possible gropings the unidentified suspect may be connected with, police said.
