D.C. Mun. Regs. tit. 6, r. 6-A700
Prisoners shall be treated with consideration. Harsh, violent, or obscene language on the part of officers toward prisoners shall not be tolerated. The use of force beyond that necessary to maintain an arrest or restrain a prisoner may subject the offending officer to removal from the force.
Immediately upon an arrest being recorded at the station, inquiry shall be made of the prisoner as to the person or persons he or she wishes notified of his or her arrest, and the station clerk shall at once make every reasonable effort to communicate with such person or persons, except where that action might serve to defeat the ends of justice or entail expense to the District of Columbia.
The officer or officers responsible for an arrest shall be present in Court or before the United States Magistrate as the case may be to prosecute or to present evidence. An appropriate charge or charges shall be placed against the persons arrested before arraignment. Any officer who fails to be present in court to prosecute a case, or any member of the force receiving a message that a case has been set for trial and fails to promptly notify the witnesses of same shall be cited before the trial board.
Where the condition of a prisoner is such that it is difficult to determine whether he or she is ill or intoxicated, or when a prisoner is taken ill in a station, he or she shall be immediately conveyed to a hospital.
Female prisoners, subject to detention by the police, shall not be confined at police stations, but shall be immediately conveyed to the House of Detention; Provided, that no part of this section shall be held to apply to female prisoners under the age of eighteen (18) years, who shall be detained in accordance with the provisions of this manual. The House of Detention is maintained by the Department of Corrections for the detention of women over eighteen (18) years of age arrested by the police, held as witnesses, or held pending final investigation or examination.
No one except persons duly authorized shall be permitted to visit or converse with a prisoner while confined at a station house and, except as to members of the force and counsel for prisoners, the visit and conversation shall be in the presence and hearing of the officer in charge or an officer designated by him or her.
When an attorney visits a station for the purpose of interviewing a client who is being held as a prisoner, the client shall, if requested and if practicable, be brought from the cell room and afforded every reasonable opportunity for confidential consultation with the attorney, consistent with proper safeguards against escape or the commission of any unlawful act.
