BROOKLYN - Police are asking the public to help identify a man who is accused of touching a woman inappropriately on the Q train.

The 38-year-old victim says the man rubbed his arm against her breast several times earlier this month, then ran away at the Barclays Center stop.

Authorities released a picture of the man in an effort that someone will recognize him.

Anyone who recognizes the man is urged to call Crime Stoppers at 1-800-577-TIPS.
