Earlier: Leicester forward Jamie Vardy has hit out at "shocking and vile" Twitter trolls who made threats against his one-year-old daughter.
The graphic abuse came after the Leicester striker's fiancee posted pictures of the toddler wearing a Foxes shirt ahead of their match against Southampton on Sunday.
Rebekah Nicholson tweeted the shots of her daughter wearing the blue T-shirt with "Daddy" emblazoned on the back, which prompted shocking threats on the social networking site.
She responded to one: "There are no words for people like you! You need locking up."
Vardy posted a screenshot of the threats, with the words "shocking and vile".
Police are in contact with Vardy's club Leicester over the abuse.
A spokeswoman for Leicestershire Police said: "We are aware of the tweets and are liaising with the club. No formal complaint has yet been made."
She added that if a complaint is made, the force will launch an investigation.
