Police are looking for a man who they say grabbed an iPhone out of a subway rider's shirt pocket in Upper Manhattan last week.
They say they have surveillance video of the suspect walking up behind the 37-year-old woman in the West 157th Street station on the 1 line on Friday morning.
He then grabbed her iPhone and then pushed her to the ground.
She injured her wrist and knee in the fall.
The man is described as about 20 years old, 5-feet-6-inches to 5-feet-8-inches tall with a medium build.
Anyone with information on the case should contact the Crime Stoppers hotline at 1-800-577-TIPS, or text CRIMES and then enter TIP577, or visit www.nypdcrimestoppers.com.
