Twitter closes accounts over child porn
People reported the accounts to Greater Manchester Police and North Yorkshire Police. It was unclear whether the images were uploaded from Britain.
"We have received around 30 reports to the centre about these Twitter accounts. The accounts have now been disabled by Twitter," the Child Exploitation and Online Protection Centre said.
A statement from Twitter said: "We do not tolerate child pornography on Twitter. When we are made aware of such images they will be removed from the site without further notice."
