A man who was jailed along with London Bridge terrorist Usman Khan has been arrested by counter terror police on suspicion of preparing terrorist attacks.

Nazam Hussain, 34, was a co-conspirator in the plot to blow up the London Stock Exchange in 2010 with Khan, who was shot dead by police on Friday after he'd killed two people and stabbed three others.

His arrest comes as police review terrorists on licence following the London Bridge attack.

He was detained in Stoke-on-Trent by officers from the West Midlands Counter Terrorism Unit.

Hussain is one of 74 convicted terrorists who were being vetted after Friday's attack.

Khan and Hussain were close friends who grew up together in Stoke-on-Trent, Staffordshire.

They were reportedly influenced by hate preacher Anjem Choudary and his al-Muhajiroun group and the gang who called themselves the Nine Lions, were from Stoke, Cardiff and London.

They planned to establish a "terrorist military training facility" on land owned by Khan's family in Kashmir, according to the judge's sentencing remarks.

At 19, Khan was the youngest member of the group.

The nine were later convicted for a complex plot to set off bombs at the London Stock Exchange and around pubs in Stoke.

They had a list of potential targets, including Boris Johnson (who was the then Mayor of London) and two Rabbis as well as the Dean of St Paul's Cathedral in London and the US embassy in London.

Hussain and Khan had been planning to travel to Kashmir in January 2011 in order to establish the terrorist military training facility.

But their plot was foiled when they were arrested in a series of co-ordinated police raids in January 2010, just weeks before the pair were due to leave for Pakistan.

After their sentencing in February 2012, Mr Justice Wilkie described them as the "more serious and effective terrorists" of the group.

They were given indeterminate sentences by the judge for public protection.

However, by April 2013, the pair had successfully appealed against sentence and were instead given 16-year sentences and they both were eligible for release on licence in December 2018.

The court of appeal judgement said the groups were "clearly considering a range of possibilities including fundraising for the establishment of a military training madrasa in Pakistan, where they would undertake training themselves."

Khan moved to Stafford and Hussain returned to his family home in Stoke.
