AN obsessed One Direction fan has allegedly killed her pet dog after the band refused to message her on Twitter.

The girl was sending the tweets to the band’s account under the handle @illumivato.

She initially tweeted the band’s account saying “Follow me or I'll break my dog's neck”.

She accompanied the message by a picture of a hand choking a tiny Chihuahua on the ground.

The band, who receive millions of messages every day on the site, did not reply to her tweet.

Several days later she tweeted band member Liam Payne with the message “I love you. Follow me. My dog has just died.”

The tweet was accompanied by the disturbing image of a girl hugging what appeared to be a dead Chihuahua.

She has been the target of criticism from other users on the site – with some suggesting the pictures were a hoax.

Twitter has since suspended the user’s account and has launched an investigation.
