If you were arrested under an arrest warrant, it indicates that an investigation against you had been conducted by the law enforcement and a prosecutor had submitted a sworn statement of the lead investigator to a judge, and a judge had signed off a warrant for your arrest. After you are arrested, you should remain silent and if you were questioned, you should request to speak with your lawyer or have the court appoint a lawyer. If you were arrested without a warrant, you should request a phone call to your lawyer or to a relative who can help you find a lawyer. It is important to know that any statements made by you can used against you but your silence cannot be used against you. The law enforcement officers are trained to use different techniques for questioning and stressing you out. It is important that you remember to remain calm and tell them that you need to see your lawyer.
