Police have put out surveillance pictures of the man wanted for stabbing a woman with a needle inside a Manhattan subway station earlier this week.

Investigators say the man seen here bumped into the victim just before 7 o'clock Wednesday night at the 49th Street R station.

Right after, they say the woman felt a pain in her right arm and went to the hospital where a red mark was discovered on her skin.

She was treated at the hospital and released.

Anyone with information on either case should contact the Crime Stoppers hotline at 1-800-577-TIPS, or text CRIMES and then enter TIP577, or visit www.crimestoppers.com.
