Two men and a woman were hospitalized early Saturday when a shooting erupted at a Brooklyn Dominican restaurant, police said. Cops called to El Nuevo Tipico restaurant at the corner of Fulton and Ashford Sts. in Cypress Hills at 1:10 a.m. found a 37-year-old man and a 27-year-old woman inside suffering from gunshot wounds. The man suffered a graze wound to the stomach, police said. The woman had been shot twice in the leg. The woman was rushed to Brookdale University Medical Center, where she’s expected to survive. The male victim was taken to Jamaica Hospital with a minor wound, cops said. A short time later, a 38-year-old man walked into the 75th Precinct station house  — about a mile from the restaurant — with a gunshot wound to his hand. The man claimed he had been wounded in the El Nuevo Tipico shooting and was taken to an area hospital for treatment. The three victims were shot during an argument inside the restaurant, cops said. No arrests have been made. The gunman was described by witnesses as Hispanic in his 50s or 60s, according to initial reports. He was last seen wearing a black jacket, white T-shirt and was sporting a grey baseball cap. Cops on Saturday were scouring the area for surveillance footage that could help them track and identify the shooter.
