The NYPD says a 51-year-old man is wanted for two separate assault incidents that took place in August in Brooklyn.

Police identified the suspect as Shawn Alexander. Authorities say Alexander struck a 28-year-old man in the head with a handgun on Aug. 2. near 179 Lott Ave.

Alexander shot that same man in the head on Aug. 3 in front of 510 Thatford Ave., and also shot a 29-year-old man in the arm.

The 28-year-old victim was taken to Brookdale Hospital in critical condition. No word has been given on his current status.

Alexander is still at large. Anyone with information on Alexander's whereabouts is asked to contact police.
