A horrified mother has issued a warning to other parents after her six-year-old daughter was sent explicit messages from men on a mobile gaming app.

Jemma Casey's daughter Morgan was sent a string of indecent messages on the app Roblox from men trying to lure her to their homes.

Ms Casey wrote a Facebook post about the app which amassed tens of thousands of shares - and she was inundated with responses from other parents whose children were also sent x-rated messages.

Ms Casey from Fife in Scotland, deleted the app from Morgan's iPad upon discovering the series of messages.

The 24-year-old said: 'I felt physically sick when I saw some of the messages she'd received.

'There was one calling her 'bae' and asking for her to call them 'daddy'. There was other stuff that was worse and because Morgan thought it was just coming from characters in the game, she replied.

'She downloaded it about three months ago so she and her big cousin could play it together.

'One day she turned to me and said: 'Mummy, somebody messaged me this morning.' He was asking her to go to his house.

'I took it off her straight away. I was terrified. She had loads of messages from strangers. I cried and I felt sick.

'It's frightening that a total stranger can send messages like that to young kids without being stopped.

'I'm disgusted by what I've seen. It could be used for grooming by paedophiles and all sorts. The safety needs addressing.'

Jackie Gordine said her eight-year-old daughter Daisy was also contacted through the app.

The 43-year-old from Sunderland, Tyne and Wear, said: 'We check Daisy's iPad for safety now and again but we had no idea about these messages.

'It was only when I saw Jemma's post on Facebook that I found out Roblox had a chat feature, and sure enough when I had a look she had a message from a total stranger.

'It said: "Hello cupcake, do you want to meet up?" Thankfully it was unopened and Daisy was totally oblivious to it but it's scary to think about what might have happened if she had replied.

'As a parent it's hard enough keeping kids safe without apps like this allowing total strangers access to kids.

'It's hard to explain the meaning of it to Daisy but we've deleted the app and warned her about the dangers of talking to strangers.'

Denise Keen, 45, also had to delete the Roblox app after a user asked her 11-year-old son Jaydon where he lived.

Denise, a personal assistant from Stoke-on-Trent, Staffordshire, said: 'Kids are so innocent and they think all the people on these games just want to be their friend.

'Jaydon was engrossed with this game. You can tell a lot of these messages are from adults out to get something. It's scary.'

A spokesperson for Roblox said: 'The safety of our community is a top priority and we're constantly assessing and improving our trust and safety measures.

'There are several safeguards in place to protect our users that utilise current technology and human oversight.

'We have instituted a best-of-breed, third-party software system created specifically to find offensive language and flag it. For users that are under the age of 13, these filters are set to block any sharing of personal identifiable information.

'All accounts for users that are under the age of 13 are set to only communicate with friends. Only friends in the approved friend's list can personal message, invite another user into games, or to join a VIP server.

'If users or their parents are witnessing any bad behaviour in the game, we urge them to flag the 'abuse report' function in the game so that these participants can be handled by the Roblox team.

'This is a priority for us. We want all users to be safe on Roblox, and we will continue to invest in the safety of the game so it is a positive, productive, fun and protected space for our community.'
