Police have a legal duty to investigate a crime. However, you have the right to say no and remain silent.
If the police continue to ask you questions, kindly let them know you will not answer any questions without the presence of an attorney.
Individuals are not legally required to participate in police questioning. A person can simply say "no", though police may be able to continue questioning until an affirmative request for a lawyer is made.
A person not only has the right to remain silent but can also request the presence of their lawyer during any questioning, even if they are not under arrest or a suspect.
