About an hour and a half after a press conference by Massachusetts authorities telling Boston residents they could resume normal activities, the sound of gunshots rang out in Watertown, MA.

Massachusetts State police spokesman David Procopio tells the Associated Press there is "renewed activity in Watertown" is connected to the search for 19-year-old college student Dzhokhar Tsarnaev (JOH'-kahr tsahr-NY'-ev). Authorities are telling residents of the area to stay indoors.

The burst of activity came at the end of a tense day in and around Boston, and less than an hour after police announced that they were scaling back the hunt because they had come up empty-handed following an all-day search that sent thousands of SWAT team officers into the streets and paralyzed the metropolitan area.
