Until you are provided with a lawyer, remain silent and turn to Art. 51 of the Constitution of the Russian Federation - "No one shall be obliged to give evidence against himself or herself, for his or her spouse and close relatives".
Remember - assess a particular question as such that may "give evidence against you".
Say: "I believe that this question will give evidence against me, my family and relatives".
Do not yield to threats or persuasion, such as "We will open a criminal case against you for the refusal to testify", "This is not a good tactic, it will only harm you", "It is better to cooperate, otherwise the court will not believe you", etc.
