NEW YORK (CBSNewYork/AP) — The New York State Tenant Protection Unit has launched an investigation into a major city landlord over allegations that it forced Asian-American tenants to leave their rent-regulated apartments.

The Tenant Protection Unit subpoenaed Marolda Properties on Wednesday in a probe into claims the company denied basic services, refused to renew leases, brought groundless evictions and pressured tenants to accept low buyout offers.
