A 16-year-old boy was knifed Monday in an unprovoked double-stabbing attack in Queens by four masked men, police sources told the Daily News.
The teen and a 24-year-old man were both stabbed in the back around 6:44 p.m. near the Roosevelt Ave. station on 74th St. and Roosevelt Ave. in Jackson Heights, cops said.
EMS transported the victims to Elmhurst Hospital, where they were in stable condition.
Police said the four attackers were all dressed in black clothing, and wore black ski masks.
There were no immediate arrests.
