Police have arrested and charged a former convict they believe slashed another man on a subway train in Queens.

It happened on October 8 on a northbound A train at Beach 60th Street in Arverne.

Police said 31-year-old Kaiseem Tankersley seen in this surveillance video approached a 21-year-old man sitting on the train and cut his face with an unknown object before the suspect got off the train and ran off.

Tankersley is facing assault charges and violated his state parole warrant.

Police say he has three previous arrests.
