Prime Minister Theresa May raised the UK's terror threat to its highest level for a decade this week, following fears that more attacks may be imminent.

The decision came after Monday night's terror attack at Manchester Arena, where suspect Salman Abedi - a 22-year-old Manchester-born former student at Salford University, born to Libyan parents - detonated a nail bomb which killed 22 people and injured up to 120 following a concert by US pop singer Ariana Grande.

Three of Abedi's relatives have so far been detained, one in the UK and two in Libya

Leaks from a US official claim UK authorities had been warned of Abedi's increasingly radicalised views by members of his family and community in Manchester.

Further leaks, including the identity of the bomber and forensic crime scene photographs published in the New York Times, have caused a major rift between the UK and US. President Donald Trump has vowed to prosecute those responsible for the 'deeply troubling' leaks.

Home Secretary Amber Rudd has admitted that Abedi was known to UK police, and he is believed to have travelled to both Libya and Syria before returning to the UK to carry out the attack.

Security forces now believe Abedia made the bomb himself, after learning the trade in Libya. Police continue to carry out raids after fears that he may have created more than one bomb.

Islamic State have claimed responsibility for the bombing, calling Abedi a 'solider of the caliphate'.

Counter-terrorism police have now arrested eight in connection with the attack as they continue to investigate a suspected terrorist network. Abedi's 23-year-old brother was arrested in Chorlton on Tuesday, with four more arrested on Wednesday, two on Thursday and one more on Friday morning.

A police statement says a woman arrested in Blackley on Wednesday evening has since been released without charge.

Meanwhile, relatives of Abedi have been detained in Libya, including his father, Ramadan Abedi, and brother, Hashim, who Libyan authorities say was 'aware of all details' of Monday night's bombing.

On Thursday morning, a bomb squad was scrambled to a college in Hulme, however, a suspicious package was found to be a false alarm.

On Wednesday, heavily armed police entered the Granby House apartment block in a Manchester city centre. Officers were reportedly seen emerging with packages. This follows an armed raid on another property in Fallowfield on Tuesday, where police carried out a controlled explosion.

Following the terror threat upgrade, the government has deployed 1000 troops to UK streets as a precaution and to alleviate the strain on UK armed police forces.

It is only the third time the terror threat has been raised to 'critical'. The previous two came in 2006, when police foiled plans to attack transatlantic flights, and in 2005, following attempts to bomb a nightclub in London.
