Declan George-Candiani, 26, of Streatham, was stopped at Stansted Airport by counter-terrorism police on August 13, 2024.

After the contents of his phone were analysed, he was arrested and a search of his home was carried out, in which an iPad was seized.

Detectives from the Met’s Counter Terrorism Command found documents likely to be useful to someone committing or preparing an act of terrorism.

These included guides on how to commit "lone wolf" attacks.

The Metropolitan Police were called by London Fire Brigade to a multi-occupancy house in Glenister Park Road, Streatham, shortly after 7pm on Sunday, where they found a 49-year-old man dead inside.

On Monday a 34-year-old woman was arrested on suspicion of murder and arson with intent to endanger life.

She remains in custody at a south London police station.

The man’s next of kin have been informed and are being supported by family liaison officers.

Police have appealed for witnesses and said they are treating it as an isolated incident.
