Police: Man assaulted 2 people with a fire extinguisher in 2 separate incidents

The NYPD is currently investigating an ongoing hate crime pattern in Brooklyn in which a man used a fire extinguisher to assault two people.
The two incidents both took place within minutes of each other on Sunday morning. Surveillance video from the scene of one incident shows a man approaching a 72-year-old male from behind before spraying him with a fire extinguisher. 
The suspect then fled on foot from the scene. The second incident took place close by and involved a 66-year-old man being sprayed by a fire extinguisher before being punched.  
Anyone with information on the incident is asked to call Crime Stoppers at 1-800-577-TIPS (8477).
