City’s new No 7 posted a picture smiling with a club scarf on Tuesday – which provoked uproar from some on Merseyside.

One user mitch.hughes wrote: ‘When you play at Anfield I hope you score a goal and celebrate because people will come for you, they will hunt you down into a tiny corner by yourself! No money to save you this time, you’ll probably be killed! By yourself, in a corner, no one will come for you because think about what you’ve done and the person you’ve become from fame and money…’

On Monday it was revealed that police have opened an investigation into the online abuse aimed at Sterling after the most expensive English player of all time received racial slurs, and threats against his three-year-old daughter, Melody-Rose too.

One user, @Bestellia, tweeted on Sunday evening: ‘I’m going to hunt your daughter down and lock her up you f****** n*****! Betraying my club for money, typical f****** b*****!’

While @xRaheemGo wrote: ‘I still hope to see Sterling in a red kit again. Not playing for Liverpool, but his City kit being soaked in his own blood. That’d be nice.’

@MediopakiEN tweeted: good riddance to that n***** sterling’, while @patricolfcryer wrote: ‘Glad sterling’s gone hope he flops at city big headed little c*** his agent can f*** himself too’.

Sterling was also referred to as a ‘c***’ in a number of other messages posted to Twitter, with his representative, Aidy Ward, also coming in for abuse from supporters.

A Merseyside Police spokesman said: ‘The language used in these tweets is abhorrent.

‘We are taking the incident extremely seriously and an investigation by detectives in Liverpool CID is on-going.

‘People who use the Internet to target others and who commit criminal offences such as harassment or hate crime in doing so are not beyond the law and can expect to be brought to justice.’

Earlier this month, teenager Joe Adams was sent hundreds of abusive messages by fans who believed his phone number belonged to Sterling.

The 17-year-old received 500 calls and 300 texts after his number was posted online, with at least one message reading: ‘Kill yourself’.

Adams, who was sent racist abuse according to his father, told The Sun: ‘When I realised what it was all about I just found it a bit strange.’
