Coronation Street star Shobna Gulati was left horrified when her final day on the show was ruined by a racist twitter troll.

The departing actress, who has played Sunita Alahan in the ITV soap since 2001, was targeted by Rob Murray who made sick comments on the social networking site.

Using the twitter handle @Rob_Murr19 he said: "Thank God d Paki's leavin... Hate her."

The 45-year-old star responded to the abuse by retweeting the vile message to her 18,000 followers, and added: "Ok tweet ta dees hes all yours racist".

According to the Sun, Murray, from Dublin, had taunted Gulati after co-star Michelle Keegan (who plays Tina McIntyre) tweeted a thank you for cupcakes she gave the cast on her last day.

This is not the first time the soap star, born in Oldham to Indian parents, has been a victim of online bullying.

In June 2012 she quit Twitter briefly after suffering a barrage of "violent" racist abuse.

Internet trolls mutilated photographs of her and posted them online with sick comments.

"Being racially abused on Twitter really shook me up. It felt like going back in time to the 1970s," she said at the time.

"It put me in mind of a psycho - like a horror movie. I just decided enough was enough."
