Boston police are investigating threats against department personnel that may be linked to the Occupy Boston movement, the commissioner said today.

In a brief statement, Police Commissioner Edward F. Davis confirmed the investigation but would not dislcose the nature of the threats. He also did not identify who was targeted.

“The Boston Police Department is investigating harassment attempts and threats directed at department personnel,” Davis said. “These threats appear to be generated by those either involved [in] or sympathetic with the Occupy Boston movement ... We are taking the appropriate steps to address any potential concerns.”

While Occupy demonstrators and the officers monitoring them have generally avoided clashes in the tent city in Dewey Square since the movement began, police did arrest more than 140 protesters two weeks ago in an adjacent area of the Rose Fitzgerald Kennedy Greenway.

Last week, the hacker group “Anonymous” said it infiltrated a Boston police union website and posted officers’ email addresses and passwords online in retaliation for the arrests, which the group said were brutal.

An email to the Occupy Boston media team seeking comment on the threat investigation was not immediately returned today.
