Former Brit school of Performing Arts student Declan George Candiani, 26, was stopped by counter-terrorism police at Stansted airport as he attempted to go on holiday to Finland with his girlfriend, on August 13 2024.

On seeing the contents of his phone, officers arrested him and searched the home he shares with his mother in Streatham, south-west London.

An examination of Candiani’s iPhone and iPad revealed a cache of extreme right-wing material included “manifestos” of mass killers and documents advocating the use of serious violence to achieve white supremacy.

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.
