Brooklyn, NY - A 25 year-old Orthodox Jewish woman from Crown Heights has filed a religious discrimination lawsuit in Manhattan federal court claiming she was threatened with arrest and had her membership revoked by a local gym for observing her religious dictates and dressing modestly while working out.

NYPOST.com reports that Yosefa Jalal, who, according to court papers, “observes the Jewish rules of modesty,” claims she joined the women-only fitness chain Lucille Roberts in 2011 and started working out wearing modest clothing—-including skirts, tights and long sleeves—-at several of the chain’s Brooklyn locations without incident.

However, at the gym’s Kings Highway location in 2013, and once again the following year, Yosefa was told she could no longer wear a skirt if she wanted to continue to use the facilities.

After switching to Lucille Roberts’ Flatbush Avenue location, Jalal was subsequently confronted by a manager who threatened her with arrest on trespassing charges for “inappropriate attire” due to her skirt.

Shortly thereafter Jalal was informed that her membership had been revoked.

Jalal’s lawyer called the gym’s actions “completely indefensible.”

An attorney for Lucille Roberts declined comment.
