Siraj Yassin Abdullah Ali, the July 2005 terrorist still lives in London.

Siraj Yassin Abdullah Ali, the fanatical terrorist has escaped being thrown out of the UK because it would breach his human rights.

Siraj Yassin Abdullah Ali, graded the highest possible risk to the public, was released after serving just half of his nine-year sentence for helping the July 21 bombers.

The terrorist now mingles freely among the Londoners his co-plotters tried to kill six years ago.

The UK Government officials are desperate to deport the Islamic fundamentalist back to his native Eritrea but have been told they cannot because he could face “inhumane treatment or punishment”.

Siraj Yassin Abdullah Ali was convicted of helping a gang of five Al Qaeda suicide bombers in their bid to repeat the carnage of the attacks of July 7, 2005, two weeks later.

Graham Foulkes, whose 22-year-old son David was killed on July 7, said:

“These people were plotting to commit mass murder – what about the human rights of victims and families?

“These people had no consideration for the women and children they were trying to kill. How can they claim we should look after and support them?”

The case is the latest to highlight how human rights laws have left the authorities powerless to remove some terrorists and convicted criminals.

Imposed by unaccountable European judges, they place the rights of the most dangerous wrongdoers above the risks faced by ordinary people.

The five would-be suicide bombers were jailed for life after trying to detonate bombs at Shepherd’s Bush, Warren Street and Oval Tube stations and on a bus in Shoreditch.

Siraj Yassin Abdullah Ali, 35, knew about the potentially murderous July 21 conspiracy and helped the fanatics clear up their explosives factory.

The terrorist was jailed for 12 years in February 2008 for aiding and abetting the Al Qaeda cell. Judge Paul Worsley QC said he must have “harboured the hope” the bombers would “destroy society as we know it”.

The sentence was reduced to nine years on appeal and after time Siraj Yassin Abdullah Ali spent in jail while awaiting trial was taken into account, he was automatically released on licence several weeks ago. The terrorist is now living at a bail hostel on a leafy residential street in north-west London. He has been seen travelling on the Tube and catching buses.

With music headphones plugged into his ears and a bag slung casually across his shoulder, he appeared to be caught on camera chatting on a mobile phone.

It is understood that Siraj Yassin Abdullah Ali is being monitored around the clock and must obey a curfew and other conditions, including a ban on using the internet.

Ali is the second high-risk terrorist linked to the July 21 attacks to win the right to remain in the UK on human rights grounds in recent weeks.

Ismail Abdurahman, 28, who hid would-be bomber Hussain Osman for three days, escaped being deported to his native Somalia after judges feared for his safety. Ismail Abdurahman is also living at a bail hostel in London despite the protests of police and Home Office officials.

The release of Ali and Abdurahman underlines the challenges faced by police, probation and MI5. There are fears that they will be stretched to the limit as they try to monitor dozens of freed fanatics in the run-up to the Olympics next year.

Research by one think-tank found that more than 230 people have been convicted of terrorist offences since 2001, but only around 100 remain in prison.

Under Article 3 of both the European Convention on Human Rights, and Labour’s Human Rights Act, individuals are protected against torture, inhuman or degrading treatment.

The clause allows foreign terror suspects to fight deportation on the grounds that they would be tortured in their home countries if returned.

Tory MP Priti Patel said: ‘This is yet another example of how we have got to abolish this appalling human rights legislation that allows terrorists and violent criminals to waltz out of prison and stay in our country.

“They should be deported instantly back to where they came from.”

Solicitor Cliff Tibber, who represents the families of several July 7 victims, said: “There is no doubt it is uncomfortable for the families to see someone like this back on the streets after what feels like an extremely short period of time.”

A UK Border Agency spokesman said: “We will do everything we can to remove this individual from the UK and are extremely disappointed by the court’s decision to grant bail, which we vigorously opposed.

“In the meantime, we are working closely with public protection agencies to ensure that appropriate monitoring is in place.”

An UK Ministry of Justice spokesman insisted that public protection remains “top priority” and that serious offenders face “strict” controls and conditions.
