Los Angeles - Robin Williams' daughter has quit Twitter.
Grieving Zelda Williams was left sickened when she received abusive messages from two users, who also sent her photoshopped pictures of her father - who took his own life on Monday - supposedly after his death.
She first urged her followers to report the trolls, before announcing she was taking a break from the social media site, possibly forever.
She wrote in a tweet which she then deleted: "Please report @PimpStory @MrGoosebuster. I'm shaking. I can't. Please. Twitter requires a link and I won't open it. Don't either. Please (sic)"
She then wrote: "I'm sorry. I should've risen above. Deleting this from my devices for a good long time, maybe forever. Time will tell. Goodbye."
The two users' accounts have now been suspended.
Following her father's shock death, 25-year-old Zelda used the social network to pay tribute to him.
She shared a quote from Antoine de Saint-Exupéry's literary classic The Little Prince that reads: "You - you alone will have the stars as no one else has them... In one of the stars I shall be living. In one of them I shall be laughing. And so it will be as if all the stars were laughing, when you look at the sky at night... You - only you will have stars that can laugh."
She added: "I love you. I miss you. I'll try to keep looking up, Z."
She later released a moving statement in honour of her father, as did her half-brother Zak, 31, younger brother Cody, 22, and her mother - the actor's second wife - Marsha Garces.
