London: Security services in the UK are hot on the heels of a British Islamic State (ISIS) terror suspect in Turkey after he mistakenly disclosed his whereabouts by joining the Linkedin professional network.
Rabah Tahari, 46, from Birmingham is believed to have recruited the so-called "Jihadi John" British Muslim terrorist as the leader of an extremist group linked to Al Qaeda.
British and Turkish security services are concerned that Tahari has moved to Turkey where he gave away his location when he joined Linkedin recently.
There are growing fears that Tahari, 46, who is the leader of a network of fighters, will make his way back to Europe to carry out terrorist attacks, reported 'The Sunday Telegraph'.
It is estimated that up to 50 British terrorists are hiding out in Turkey, where they can plan terror attacks against the West safe from allied bombing.
Tahari has taken part in key operations in Syria where he and his fighters were trained to use a range of weaponry.
In November, the Turkish security services captured Aine Davis who was reported this week to be one of the so called "Beatles" who guarded foreign hostages who were later slaughtered by Mohammed Emwazi or Jihadi John.
Davis is now in custody in Turkey where he is awaiting extradition to Britain.
He was arrested alongside a number of other unnamed jihadists suspected of planning an attack to coincide with those that killed 129 people in Paris in November.
Tahari's group, Kateeba al-Kawthar, comprises fighters from more than 20 nations all seeking to impose an Islamic state.
Emwazi is thought to have followed other members of his Islamist network who left London in 2012 to join up with Tahari in Syria.
He later left Tahari with a group of other extremists to join ISIS where he took part in the execution of British and American prisoners.
In 2014 UK Home Office minister James Brokenshire said, "Kateeba al-Kawthar describes itself as a group of mujaheddin from more than 20 countries that seeks a just as it perversely says Islamic nation. It is an armed terrorist group fighting to establish an Islamic state in Syria."
"Abu Musab, who is also known as Rabah Tahari, a western mujahed commander, is its leader. The group is believed to have attracted a number of western foreign fighters, and it has released YouTube footage that encourages travel to Syria and asks Muslims to support the fighters," James said.
