(NECN) - The Boston Police Department has been accused of illegally spying on anti-war groups.
The allegations in a lawsuit have been filed by the National Lawyers Guild and the American Civil Liberties Union.
According to the court documents, Boston Police conducted surveillance on anti-war groups - between 2007 and 2008 - that have no affiliation with crime or terrorism.
Civil rights groups say that was a violation of federal regulations.
In a statement, the Boston Police Department said it does not conduct surveillance without specific information on suspected criminal activity.
