Police are looking for two men believed to be in their 20s who have shot four people during four separate robbery attempts in the Bronx dating back to October.

In most of the shootings, the suspects approach the victim on the street between the hours of 11 p.m. and 3:30 a.m., brandish a gun and demand cash or property.

When the victim either tries to run or refuses to hand over money, one of the suspects shoots him and both suspects flee.

All of the victims were taken to the hospital in stable condition after being shot; three were shot in the leg and one was hit in the neck. 

The suspects did not make off with cash or property in any of the four incidents.  

The most recent attempted robbery was Feb. 8 at 3:30 a.m. on the New England Thruway near East 222nd Street. The pattern dates back to Oct. 25; only one of the suspects was involved in that incident and police released a sketch of him (above).

Anyone with information about the shootings or attempted robberies is asked to call the NYPD's Crime Stoppers Hotline at (800) 577-TIPS.
