French police are investigating 'new death threats' targeted at Charlie Hebdo

'The messages raise the idea of killing several members of the editorial team,' says a source close to the investigation

The threats reportedly said several editorial team members would be targets

French police are probing death threats made towards the satirical magazine Charlie Hebdo, according to reports in France.

A source close to the investigation told Le Parisien newspaper the first threat was made on the magazine's Facebook account before being removed by an unknown person.

The threat reportedly said several editorial team members would be targets in an attack.

A similar second threat was sent to the magazine's editor a few days later, the source said.

The source told the paper: "The messages raise the idea of killing several members of the editorial team, again."

Charlie Hebdo's Paris offices were attacked on 7 January 2015 by two brothers, Saïd and Chérif Kouachi, who shot dead 11 people and injured a further 11.

Since the attacks, the magazine has been placed under enhanced security.

The magazine is now based at a top secret location, after initially being moved to the offices of the Libération newspaper, the Local reports.
