Twitter revealed that it has closed over half a dozen accounts after it was brought to notice that they contained images of child abuse.
According to a Children charity group, NSPCC, the graphic pictures were apparently made public after hacking groups claimed to have broken into private accounts to expose their indecent content.
The charity said it received a 'flurry' of reports overnight relating to at least half a dozen Twitter accounts which were later disabled.
According to the Guardian, the accounts will now be probed in the US, where the micro-blogging site is based.
The charity group said that the hackers apparently opened up a number of private accounts, which were previously kept hidden from public view
It remains unclear whether any of the images were uploaded by a British user or a user based abroad, the paper said.
