NORTHAMPTON — Police are investigating incidents in which the names and personal information of employees from the defense contractor L3Harris in Northampton were posted on the windows and doors of downtown businesses and electrical boxes late Tuesday night.

Paul Serio, who owns Serio’s Pharmacy at 63 State St., said he arrived at work Tuesday morning to find seven posters depicting the photos, names, addresses, salaries and phone numbers of four L3Harris employees glued to his window. He said the flowers in his flower boxes had been ripped out as well and his miniature American flags were missing.

Someone “also then ripped out some of the plants in our flower boxes. I’m assuming it was all done at the same time, but we can’t know for sure. There was vandalism to the flower boxes as well,” Serio said. “Memorial Day weekend, I had some small American flags in the boxes. I don’t know if they were protesting that, because they’ve all been removed one-by-one. There were six flags out there all together, and now they’re all gone.”

Northampton Police Capt. Corey Robinson explained Wednesday morning that the vandal or vandals glued posters at 1 Market St., 63 State St., the Pioneer Valley Transit Authority (PVTA) bus stop at Pulaski Park, an electrical box at 1 Pearl Street, the intersection of Old South Street and South Street and at the L3Harris headquarters at 50 Prince St.

L3Harris, a $60-$65 billion defense contractor that works with both the Israeli military and the U.S. Immigration and Customs Enforcement (ICE), among other clients, has been the subject of more than a dozen protests over the last two years.

Robinson said several L3Harris employees were targeted in posters that displayed varying degrees of personal information.

“We’re getting reports of several instances where some unknown actors posted information regarding l3 Harris employees across the city,” Robinson said. “I don’t know at this point, but I think the goal was not so much to target the businesses, but was to dox the employees of L3Harris.”

Jennifer Scarlott, an anti-war activist with River Valley for Palestine and Demilitarize Western Mass, said that while she can not claim responsibility for the protest activism, and is unaware of who might be responsible, she “applauds” it.

“I think L3Harris, as a global weapons manufacturer, is a bad actor and should be closed down not only in Northampton but everywhere,” Scarlott said. “I applaud this. It’s engaging and valid activism that I appreciate.”

Robinson said that those responsible for the posters could face charges of vandalism, conspiracy and criminal harassment.

An L3 Harris employee declined to comment on the matter when approached at the business’ headquarters Wednesday afternoon. Attempts to reach an L3Harris spokesperson by phone on Wednesday were unsuccessful.
