Police have released a sketch of the suspect.

A wave of attacks, where the perpetrator attempts to knock out an unsuspecting stranger with a single blow, began in Crown Heights in October. Police had previously beefed up patrols in some of the communities that have seen several incidents.

The incident was one of two suspected “knockout game” incidents in Brooklyn on Saturday, according to a New York Daily News report. In the second incident, a group of teens blocked a 47-year-old woman’s path at Hendrix Street and Pitkin Avenue in East New York around 6:45 p.m., and a girl in the group punched the woman in the head and knocked her down, police told the newspaper.

Anyone with information in the latest attack was asked to call the NYPD Crime Stoppers at (800) 577-TIPS, log onto the Crime Stoppers website, or text tips to 247637 (CRIMES) and enter TIP577.
