Massachusetts prosecutors on Wednesday dropped a criminal case accusing former "House of Cards" star Kevin Spacey of sexually assaulting an 18-year-old man at a Nantucket bar in 2016 after the alleged victim refused to testify.

Prosecutors said they made the decision to drop the felony indecent assault and battery charge against the Oscar winner after the alleged victim invoked his right under the U.S. Constitution against giving self-incriminating testimony.

Spacey's lawyers had previously accused the man of deleting text messages that would support the actor's defense. The man invoked his Fifth Amendment rights during a hearing earlier this month concerning the whereabouts of his cellphone, which was missing.
