A man and a woman were randomly attacked in separate incidents in the Bronx when a blade-wielding madman walked up to them and slashed them across the face and neck, cops said.

The thug never said a word to either victim and didn’t try to steal anything, cops said.

The 60-year-old man was attacked Sunday evening on Boston Road in Williamsbridge and a 65-year-old woman on Monday around 1:10 p.m. on the same block.
