NEW BEDFORD — New Bedford Police are looking for the public’s help in locating 37-year-old Heather Perkins, who is being sought in connection with bomb threats and threats of violence.

Perkins is five-foot-four, about 147 pounds, with brown hair (although she may have changed it to blonde) and hazel eyes. She has no current address, but previously lived at 199 East Clinton Street and 116 Ruth Street in New Bedford.

An arrest warrant has been secured for Perkins, who is a suspect in five threats received in the city within the last week.

One of the threats, received Friday, caused City Hall to be evacuated for a brief period.

Dartmouth Police have also confirmed that Perkins is being sought for a bomb threat made toward their department on Sunday.

Overally, nearly 25 police departments as well as the University of Massachusetts Dartmouth, Bridgewater State University and Springfield College have also received threats.

Perkins may also be connected to threats received by WBSM employees Monday morning, warning them of a boyfriend that was coming to the station to murder them. Although a different name was used in the emails, it mentions Perkins' last known address.

Anyone with information about Perkins is asked to contact New Bedford police by calling (508) 991-6350 or the anonymous tip line at (508) 992-7463 or e-mailing tip@newbedfordpd.com.
