Soon after the attack, twisted Jihadi accounts began celebrating its devastating effects.
The sick account, Owys 663, threatened terror in Manchester just one hour before the incident.
The message read: “Are you just forget our threat [sic]? This is the just terror.”
The owner of the account then celebrated as news of the incident spread.
It continued: “In the name of Allah the merciful. You unbelievers, you see the day you pay the tribute to the Islamic state away and see it soon, God willing.”
The account has not been verified and could well be a sick troll, trying to stir up hatred.
Twitter later removed the account.
