NEW YORK - The Legal Aid Society is urging the City Council to stop the NYPD's practice of collecting DNA.

In a letter written to Council Speaker Corey Johnson, the Legal Aid Society claims collecting DNA is "racially biased" particularly to people of color.

They cite the recent murder case of jogger Karina Vetrano as an example of the practice - 360 black men from Howard Beach were swabbed for DNA in the case.

Their samples supposedly were then entered into a databank.

DNA evidence was controversial during the Vetrano trial.

Chanel Lewis' lawyers claimed the evidence was tainted.

Lewis was convicted of first and second degree murder and sexual abuse on April 1, and faces up to life in prison.

The Legal Aid Society is asking for the City Council to hold a hearing as a follow up to the letter.
