Police: Man wanted for screwdriver assault

The NYPD is currently searching for a man who assaulted a 46-year-old man with a screwdriver at a Shell gas station in Brooklyn. 
Video from the incident shows a verbal dispute break out between the victim and suspect, when the suspect punches the victim in the head numerous times before displaying a screwdriver. 
The suspect then strikes the victim multiple times around (try to stay somewhat conversational, no one would say ‘about’ the torso, they’d say ‘around’ the torso) the torso. The victim sustained one puncture wound that resulted in both of his lungs collapsing from the trauma.  
The victim was transported to Brookdale Hospital in critical but stable condition.  
The suspect fled on a Citi bike and was last seen traveling southbound on Rockaway Parkway. 
If you have any information regarding the suspect in this incident, call Crime Stoppers at 1-800-577-TIPS (8477).
