Instagram are to investigate after Republic of Ireland defender Shane Duffy was sent sectarian and abusive messages on the social media platform.

Duffy shared a screenshot of the messages, which contained sectarian insults and expletives, and mocked the death of his father last year.

In sharing the messages, the 29-year-old, who is on loan at Celtic from Brighton, commented: "There's abuse which is fine but surely there's a limit."

The user of the account, which is no longer active, reportedly posted that they had sent the messages "to see if I could get a reaction".

Duffy's revelation follows fellow Derry native and Ireland star James McClean speaking out last week about death threats and sectarian abuse he and his family have received online.

Social media networks like Facebook, which owns Instagram, and Twitter have faced calls for tougher measures against online abusers following a spate of racist messages to Premier League footballers like Manchester United Marcus Rashford.

Both have so far resisted pressure to ban anonymous user accounts. 

In Ireland, an 18-year-old Kerry man was given probation earlier this month for sending racist messages to former Arsenal and England forward Ian Wright on Instagram last year.
