The suspected mastermind behind the Jakarta Terror attack had been running a virtual jihad training camp for ISIS recruits which published bomb-making manuals and raised funds for the terror group using a PayPal account.

The operation had been running on a public website since 2013 and was only shut down by the authorities some 18 hours after the bombing and shooting spree in the Indonesian capital on Thursday.

The site was run by Bahrun Naim, a known Islamic militant who has been named by police as the co-ordinator of the attack and is currently believed to be with ISIS in Syria.

He used an image of James Bond in a post which claimed that his group deliberately caused a terror alert in Jakarta in November and another Article contained a recipe for the same type of explosive that was used by the 7/7 bombers in London in 2005.

Naim is thought to have fled to Syria last year but police have said that he was closely involved in co-ordinating Thursday’s assault in Jakarta, which ended with the five attackers killed and two other people dead.

He was first suspected by the authorities of involvement in terrorism in 2010 and was jailed for three years for possession of illegal ammunition in 2011.

Naim referred in November to a planned Paris-style attack on his website, which was taken offline on Thursday evening.

An article was called “Lessons from the French Attacks” and Naim urged followers to emulate the Paris attackers by being careful to avoid using social media and inadvertently giving away clues about plans for attacks.

A post in December contained detailed instructions on making a bomb detonators made of a TNT derivative called triacetone triperoxide (TATP), which is the same type of explosive that was used in the London Tube bombings of 2005.

Called “Questions Regarding TATP Detonators”, it noted that the two main ingredients need to make the substance could be found in many high street shops and the article went on to give tips on manufacturing it.

Another post included instructions on making a suicide bomb belt, complete with hand drawn sketches, and another showed how to make small hand grenade-type bombs with ball bearings taped around the outside to maximise casualties.

Naim also published an article about how to set up and control networks of terrorist cells like ISIS in Syria and Iraq.

He even solicited funds from supporters on one page and included a link to a PayPal account where money could be transferred using debit or credit cards.

In his last post, on 9 December, he claimed that a powerful bond exists between ISIS members who have left their homelands to wage jihad in Syria and Iraq.

At the time of writing, his site had clocked up 183,297 visits since it was started on 17 September 2013.

The contents started to become unavailable just before midnight GMT on Thursday, though many of the articles were still available on Naim’s Google+ account.

He is believed to lead a group in Syria called Katibah Nusantara, which has reportedly been involved in clashes with Kurdish forces near ISIS’s de facto capital city of Raqqah in eastern Syria.

Police in Indonesia said Naim’s goal is to unite all jihadist groups in Southeast Asia to operate under the banner of ISIS, opening a new front for the terror group.

The Jakarta attack provides further evidence of the expansion of the ISIS franchise and burnishes its credentials as a global terror group, adding to areas of operations which stretch well beyond Syria and Iraq.

ISIS officially claimed responsibility for the attack in a statement issued online on Thursday and police announced on Friday that three arrests had been made in a hunt for other terror cells.
