The Daily News has filed a $150 million racketeering lawsuit accusing its striking unions of using violence in an organized effort to win their demands or force the sale of the newspaper.

The lawsuit, filed Thursday in federal court, claims the alleged conspiracy included attempted murder, arson and robbery.Police officials have said they found no evidence of a conspiracy in 229 incidents during the 5-week-old strike.

The lawsuit says strikers are using violence to achieve one of two goals: forcing the tabloid into accepting wasteful contracts or making it accept a union buyout plan.
