While the police believe they know who the attacker was, difficult forensic work may be continuing to confirm the identity - particularly if experts have to resort to dental records and DNA.

Digital forensic teams investigate the dead man's online habits and contacts. Officers will want to build a picture of his movements from mobile phone data and financial transactions.

Bomb experts will be looking at how the device was made.

These strands may lead detectives to vital CCTV evidence and locations or witnesses that will help reveal the attacker's planning.

But the biggest priority will be to establish - if possible - whether there is any ongoing threat to the public.

Police said a man, aged 20, was arrested earlier in the Kensington area of the city and was in custody.

Three other men - aged 21, 26 and 29 - were detained on Sunday in Sutcliffe Street in Kensington.

Mr Jackson said the arrested men were believed to be "associates" of the taxi passenger.

He said officers were looking at the man's associates, his telephone records and purchases he may have made.

Officers are searching two addresses, one in Sutcliffe Street and a second at Rutland Avenue, where "significant items" had been found, police said.

A cordon is in place at both locations and eight families have been evacuated from their homes.

Police have confirmed a controlled explosion was carried out as a precaution in the Sefton Park area, close to Rutland Avenue, at about 16:00 GMT on Monday as part of the investigation but there was no wider risk to the public.

Frances Evans, who witnessed the explosion, told BBC News that three police vans and a little black van had pulled up before covering an unknown item.

"They weren't there long, probably 20 minutes max," she said. "I saw the explosion, the smoke and heard the bang."

Mr Jackson said police had linked the taxi passenger to both the addresses but were uncertain which one he lived at.

Converted Christian whose asylum claim was previously rejected...

A lot of asylum seekers convert to Christianity or say they are gay and lie about their country of origin, as the punishment for either of those in places like Syria or Iran is death, so it is harder for the UK to deport them.

Rafiq: I'm gay and I'll be shot if I'm sent back.
Me: Toby, do you wanna earn a few quid? Go see if Rafiq is gay.
