The RCMP have charged a 19-year-old London, Ont,. man following the theft of 900 social insurance numbers from Canada Revenue Agency (CRA).

Stephen Arthuro Solis-Reyes was arrested at his home "without incident" on Tuesday, the Mounties said in a press release. He faces one charge of unauthorized use of a computer and another charge of mischief in relation to data.

Canada Revenue shut down access to accounts on its website last week after the discovery of the Heartbleed bug, a flaw in OpenSSL software used to sign in to websites, which allows personal data to be stolen.

The CRA reopened access to its site earlier this week, delaying the filing deadline to May 5 to allow for lost time. But the agency announced that 900 social insurance numbers had been stolen after the bug was discovered.
