Police are investigating after six people were shot across Brooklyn in the last 12 hours.

Police say they are searching for the suspect who shot and killed a 23-year-old at the intersection of Flatbush Avenue and Fulton Street around 10 p.m. Thursday.

They say the shooter was last seen running northbound on Flatbush Avenue wearing a white hat and a black T-shirt.

Police say the 23-year-old man was shot in the shoulder and the head and rushed to the hospital, but did not survive.

Meanwhile, detectives were also busy at the Farragut Houses where just a little after 3 a.m. a 28-year-old man was shot in the neck. News 12 cameras saw dice in the street along with cups covering up what appeared to be shell casings. As of 7 a.m., the victim was as listed in critical condition, according to police.

A few hours before that, around 1:15 a.m. a 52-year-old man and a 23-year-old woman shot in what appears to be a drive-by shooting in front of 397 East 49th St. Officials say they are both being treated for gunshot wounds to their arms and are in stable condition. Police tell News 12 they are looking for a dark-colored sedan in connection to that shooting.

About two hours earlier, a 20-year-old woman was shot in the leg on Warren Street near the corner of Third Avenue in Gowanus. She told police she was standing near the corner, heard gunshots and felt pain. She is expected to survive.

In the last couple of hours, police tell News 12 a 36-year-old man walked to Woodhull Medical Center with a gunshot wound to his leg. News 12 is told he is expected to survive, but the details of what happened and where are unclear.

Investigators say they are reviewing surveillance camera footage, and as always asking anyone who might have information to call police.
