EDIT 202 1:31: It's basically been a lot of officers telling each other where they are going and general communication. Nothing new.
EDIT 201 1:30: Conference starting, link below.
EDIT 200 1:26: Correspondent /u/potato_bus says another press conference is coming up.
EDIT 199 1:21: I have heard no updates on the old man with the dead switch or the location of White Hat. I am only listening to the scanner but I do check messages for info.
EDIT 198 1:20: Apparently the 'hostage' was frightened by a police officer with a gun.
EDIT 197 1:18: House with 'hostage' was clear.
EDIT 196 1:17: They made sure the situation from 185/177 is definitely clear.
EDIT 195 1:15: "Ambulance on the way to evaluate her."
EDIT 194 1:14: People are telling me they said the hostage is safe.
EDIT 193 1:11: They are calling for an ambulance to swing by. If something was said before it I missed it.
EDIT 191 1:10: A lot of garbled messages, SWAT is stepping in.
EDIT 190 1:08: Front door opened, "we have the message".
EDIT 189 1:07: Look if the hostage taker is reading reddit instead of listening to the scanner then he's screwing himself and we're helping the police.
EDIT 188 1:05: Attempting to contact hostage taker.
EDIT 187 1:02: Possible house with hostage located.
EDIT 186 1:00: Another suspicious package reported.
EDIT 185 12:57: Situation from EDIT 177 is clear.
EDIT 184 12:56: Possible hostage situation.
EDIT 183 12:55: "Everyone take cover. No more units."
EDIT 182 12:55: "A person is being held there by gunpoint."
EDIT 181 12:54: A man is trying to get through security but has no credentials.
EDIT 180 12:53: Woman is being held by a man with a gun
EDIT 179 12:53: Again, I don't know what the specifics of 173 are. I'm not holding out. They just started talking and then said 'we don't want this on the air' and then didn't talk about any specifics.
EDIT 178 12:51: Reports are coming in that the White House situation room has been activated. I'm looking up more now on that.
EDIT 177 12:47: They are following up on another lead similar to the open basement. Stuff has been moved since they last investigated the area. (Look, do I think white hat is reading this instead of just listening to the scanner? No, but i can be a little more vague when the detail doesn't matter.)
EDIT 176 12:42: About EDIT 173, I don't really know what it is. They aren't saying many details, they are checking on a vehicle, but other than that the only details are unit number and specific locations. Which is exactly what they asked not be posted. If something happens I'll post the aftermath. And this is the first time they specifically said on the scanner not to mention something on the air.
EDIT 175 12:40: They are checking on something but not being very descriptive.
EDIT 174 12:38: There will be a controlled explosion in Cambridge later in the day as a precaution.
EDIT 173 12:35: They just said something that they don't want on air. Don't write a comment about it.
EDIT 172 12:34: I'm still listening to the scanner and not the press conference so if anything new comes out in the conference please let me know.
EDIT 171 12:33: EOD team being sent to another location.
EDIT 170 12:29: /u/potato_bus posts link to upcoming press conference. Police are very concerned about the security for the conference, or rather, making sure it is as secure as possible.
EDIT 169 12:27: Open basement door that is being checked out.
EDIT 168 12:24: /u/potato_bus said that MyFoxBoston is reporting that the helicopters are part of the FBI's Hostage Rescue Team (HRT), they are not military.
EDIT 167 12:22: CNN is confirming that the link is his twitter account:
https://twitter.com/J_tsar/EDIT 166 12:17: /u/SolusLoqui posted a link to a Guardian photo album of Boston's deserted street. Still waiting on press area to be cleared apparently.
