A 15-year-old boy was blasted in an apparent drive-by shooting in upper Manhattan late Friday afternoon, police said. The teen was struck in the buttocks around 4:30 p.m. near the intersection of W. 155th St. and Frederick Douglass Blvd. in Harlem, cops said. EMS transported the youth to Metropolita n Hospital in stable condition, according to police. The gunshot appeared to have been fired from a car last seen traveling toward Broadhurst Ave., a police source said. Cops were not immediately able to confirm the type of car, but a police source said it appeared to be a silver Infinity. The investigation is ongoing. The incident is the third shooting to happen within a roughly three-hour span on Friday afternoon in New York City. Earlier, a man was shot in the head outside a fruit stand in the Bronx around 1:48 p.m. About 40 minutes later, another man was shot in the leg outside the Smith-Ninth Sts. subway station in Brooklyn. The shootings do not appear to be related. Police ask anyone with information to call the Crime Stoppers Hotline at (800) 577-TIPS. All calls are confidential. ...read more read less
