Former NYPD Blue star Esai Morales has been told that no criminal charges will be filed against him over allegations that he sexually assaulted his ex-girlfriend.

A spokeswoman for the Los Angeles County district attorney's office has confirmed that the case has been rejected due to lack of evidence.

Elizabeth Mazzocchi claimed that Morales had raped her in April 2006. She has also sued the actor in civil court and the case is awaiting trial.

"I'm happy that my client was vindicated," Morales' attorney, Richard Charnley, explained. "He was never questioned by the police, never taken into custody, there were never any charges brought against him."

Nader Pakfar, an attorney representing Mazzocchi, said: "She stands by her allegations, absolutely." He also claimed that evidence which has yet to come to light could result in the district attorney's office reviewing its decision.

Morales played Lt Tony Rodriguez on NYPD Blue. He has also appeared in the movies Bad Boys and La Bamba.
