An exam security breach that saw A-level questions shared on Twitter has resulted in the arrests of two people.
Two further maths questions were leaked on social media in posts that promised pupils the entire Edexcel paper for £70.
The June 14 exam had to be withdrawn and replaced and the Twitter account in question was deleted.
Pearson senior vice-president Sharon Hague said that the firm is working hard to identify how the exam questions ended up online

A spokesperson for Pearson, the company that operates the exam board, said today that the Met Police have arrested two people.
They said: 'Following a serious security breach at a Centre involving the breach of an A level maths paper in advance of an exam sat on June 14, Pearson has been informed by the police that they have arrested two individuals and are detaining them for questioning.'
Pearson senior vice-president Sharon Hague said: 'We understand students are rightfully concerned and want a fair playing field.
'The actions we have taken to strengthen our security processes has enabled us, in conjunction with the police, to quickly identify those who we believe were involved in the breach and to take swift and immediate action.
'We are systematically working through all leads and, as we continue to investigate the suspects, this will enable us to further hone in on anyone that has gained an advantage, and take action accordingly. Our key priority is ensuring no students are disadvantaged in any way.'
Pearson replaced another maths A-level paper which was due to be sat by 7,000 students, in the wake of the breach.
It came after similar leaks in 2017 and 2018 when A-level maths papers were put up online ahead of the tests.
The leaks were probed by the police and evidence was passed to the Crown Prosecution Service for consideration over whether criminal charges should be brought.
Earlier this year, Pearson said it would be trialling a scheme where microchips were placed in exam packs to track the date, time and location of the bundles.
The company faces scrutiny from the regulator Ofqual, as a spokesperson branded the alleged breach 'completely unacceptable'.
Ofqual said that a team is now monitoring the investigation conducted by Pearson as well as the approach the company takes to awarding the qualification.
Officials said that they had referred the matter to the police and stressed that everyone in the exam
