The rift between Verizon Communications Inc. and its 45,000 striking employees grew wider today, CNNMoney reported, after the telecommunications giant called in the FBI to investigate allegations of sabotage.

A Verizon spokesman said more than 90 acts of sabotage have taken place since the strike began on Sunday. Saboteurs reportedly have cut phone lines, affecting the service of several thousand customers, primarily in New York and New Jersey but also in Massachusetts, Pennsylvania and Delaware.
