Person of interest in multiple stabbings across NYC being questioned, source says

NEW YORK - A person of interest is being questioned after at least five people were stabbed at random in Queens on Wednesday, a source tells CBS New York.

Three of the attacks happened Wednesday morning in Springfield Gardens. Additional attacks took place Tuesday and on Jan. 8. Police said they are also eyeing the same suspect for a stabbing on a subway in Williamsburg, Brooklyn, as well. 

"We have an unidentified individual who's walking around the street randomly stabbing people with a hunting knife. There's no connection between individuals, and it seems to be unprovoked," NYPD Chief of Patrol John Chell said.
