After three foreign offices received envelopes containing a suspicious substance on Monday night, three more received similar envelopes yesterday. First, the German Mission to the U.N. reported receiving an envelope, and later in the day, the British and Russian Missions also received envelopes. The NYPD expects more letters to be found in the coming days and Mayor Bloomberg said of the incidents, "Anybody that thinks that it's a joke is making a very bad mistake. If we apprehend you you're going to face criminal charges."
