Two Baltimore women are being held without bail after being charged with torturing and sexually assaulting another woman in Reservoir Hill, police said.

According to a police charging document, a 23-year-old woman told police that a longtime friend, Shameka Davis, 29, invited her to an apartment on Lennox St. on Jan. 23. At the apartment, the woman said Davis tied her to a chair and duct tape was placed over her mouth, and a knit hat was pulled down over her eyes, police said.

A second woman entered the apartment, who Davis called "Candice," and both began to slap her in the face. The two women cut off the victim's clothes and underwear, and sexually assaulted her while burning her with a curling iron and putting out cigarettes on her body, police said.

During the attack, the woman's cell phone and an Ice King Watch with diamonds were taken from her, police said.

The victim told police a third woman freed her and told her to leave, police say. Outside the apartment, the woman flagged down a police officer and pointed out the suspects driving away in a 2004 Honda Civic. The vehicle was being driven by a woman named Candice Newkirk, who the victim identified as one of her attackers, police said.

Police executed a search warrant on the Lennox Street apartment and found duct tape, the victim's cell phone, and other items related to the assault.

The charging document does not explain a motive for the alleged assault.

Davis and Newkirk were both charged with first-degree sexual assault, conspiracy to commit a sex offense, robbery, assault and related charges. Davis did not have an attorney listed, and an attorney for Newkirk could not immediately be reached for comment.
