Living (squatting) in a unit for more than 2 weeks - must evict?

[Achi Adamit]

This question is for anyone, but more specifically for people who own in Binghamton, NY.  Management company told me that new tenant who is receiving rent money from Catholic Charities, has been arrested, and that a squatter took his place.  When Binghamton police accompanied my manager to get him out, squatter claimed to have been living there with tenant for 5 weeks, which police sited as more than the stipulated 2 week period in which case a person (our case, a squatter) must be evicted legally.

Wondering if my fellow Binghamton investors can verify this to be true, or have any advice?
