Former CBS CEO Les Moonves

CBS (CBS) was subpoenaed by the New York County District Attorney's Office and the New York Commission on Human Rights in connection with a probe of former CEO Les Moonves, according to an SEC filing Friday.

The move comes in the wake of Moonves' departure from the company last month following a series of accusations of sexual assault and harassment against him.

The company said it is cooperating with the ongoing investigations and related inquiries.

Shares rose 90 cents, or $1.59, to close at 57.45 Friday but are down about 3% year-to-date.
