Stuck In A Mess - Illegal Subletters, Please Help!

[Steve DellaPelle]

Here is my situation.

October 2020, Tenant A moved in.

Approx. April 2021, Tenant A sublets her apartment ILLEGALLY to Tenant B (no landlord approval, lease clearly states it's illegal to sublet).

No rent is given from Tenant A or Tenant B for months.

September 2021, we find out Tenant A was collecting rent from Tenant B but not giving it to us.

By a miracle, we end up collecting every penny that was owed from Tenant A.

October 2021, Tenant A's lease ends.

Tenant B is still in the apartment.

Shocker, they do NOT have good credit and they have a prior eviction on record.

If we want to get them out in today's difficult COVID-19 landlording world, how can we go about it?
