Dutch police have questioned a security researcher who said he successfully logged into the US president's Twitter account by guessing his password.

Last month, well-known cyber investigator Victor Gevers said he had gained access to Donald Trump's Twitter account with the password 'MAGA2020!'.

The White House denied it had happened and Twitter said it had no evidence of a hack.

But Mr Gevers has now revealed more information to back up his claims.

As part of the police interrogation, Mr Gevers revealed for the first time that he had substantially more evidence of the "hack" than he had previously released.

He did not reveal exactly what information he had, but by logging in to somebody's Twitter account an attacker would in theory be able to:

  • see and send private messages
  • see tweets that the user had privately bookmarked
  • access information such as how many people the account holder had blocked

They would even be able to download an archive of all the user's data, including photos and messages.
