When the detectives are certain they have the right suspect(s), the police will take the case to their boss, who decides if there is enough for a search and/or arrest warrant (though sometimes the commanding officer will consult with the New York City District Attorney's office to see if the case is strong enough) and whether or not any backup (such as uniformed officers or an armed tactical team) is needed. The detectives will then arrest the suspects(s) and read them their miranda rights, though sometimes the police might have to chase the accused through the streets of New York.
