A Bronx man is under arrest for allegedly slashing three people on the subway.

Twenty-eight-year-old Shawn Howard is charged with assault and criminal use of a weapon.

Police say he slashed a 19-year-old man in the face aboard a C train at the Utica Avenue stop Monday night.

Investigators have now linked Howard to two other similar attacks.

They say he slashed a 21-year-old woman on the A train in Brooklyn Tuesday morning.

He allegedly did the same thing to a 23-year-old woman riding the C train Thursday afternoon.
