The New York City Police Department is hoping surveillance video will help them find a person of interest in connection with a shooting on Manhattan's Lower East Side earlier this week.

Investigators say a 22-year-old man was shot four times in the back on Rivington Street just after 7 p.m. Monday.

He is now in critical condition.

Anyone with information about the case is asked to call Crimestoppers by calling 1-800-577-TIPS, by texting TIP577 to CRIMES, or by going to NYPDCrimeStoppers.com.
