Scotland Yard Deny Hacking Of Terror Hotline
A group calling themselves Team Poison say they got into the secure phone system and recorded a conversation between officer's. They have also claimed responsibility for phone bombing the hotline with more than 700 calls.
The Met Police have since released a statement saying: "We have researched the allegation that the Anti-Terrorist Hotline had been 'hacked' and 'activists' claims that they were able to listen unrestricted to confidential communications.
"We are confident the MPS communication systems have not been breached and remain, as they always have been, secure.
"We are satisfied that any recording would have been made via the receiving handset only and not from an attack on internal systems.
