One of nine extremists convicted in 2012 alongside London Bridge terrorist Usman Khan for plotting to attack the London Stock Exchange has been arrested in Stoke-on-Trent, Sky News has learnt.
Nazam Hussain, 34, was detained on suspicion of preparation of terrorist acts after a search of his home address, following a review of terrorists released on licence in the wake of the London Bridge attack.
It comes after Khan killed two people and injured three others in a knife attack at London Bridge on Friday.
A West Midlands Police spokesman said there was "no information to suggest" the arrest was linked to the London Bridge attack and "no immediate risk to public safety".
Hussain and Khan, both from Stoke-on-Trent, were originally given indeterminate sentences with a minimum term of eight years behind bars after being convicted of terrorist offences in 2012.
But they successfully appealed against their sentences in 2013 and were given fixed terms instead.
They were both released on licence in December last year.

The force said the search warrant was executed on Saturday "in connection to a wider on-going review of existing licence conditions of convicted terrorism offenders".
As part of the investigation into the London Bridge attack, police have been searching a property in Stoke, where Khan had been based, and a block of flats in Stafford, where he is believed to have stayed.
The 28-year-old had been wearing an electronic tag when he launched his attack after being released halfway through his 16-year prison sentence over the London Stock Exchange bomb plot.
He was tackled by several members of the public – including ex-offenders and an off-duty policeman – before he was shot dead by officers on London Bridge.
It has prompted the Ministry of Justice to review the licence conditions of every convicted terrorist released from prison.
Prime Minister Boris Johnson has said the review applies to "probably about 74" people and he found it "repulsive" that terrorists like Khan could be released from prison after serving eight years.
Meanwhile, Labour leader Jeremy Corbyn told Sky News that convicted terrorists should "not necessarily" automatically serve their full prison sentences.
