A man who stockpiled dangerous chemicals at his home in Kingston.

Michael Pym-Nixson, 54, of St George's Road, Kingston was investigated after he was treated for suspicious burn injuries.

On the evening of Friday March 19, 2021 paramedics were called to Pym-Nixson's address to treat burns to his left hand which he said were caused by a firework accidentally igniting.

On the morning of Sunday March 21 officers visited Pym-Nixson's home with a search warrant and arrested him.

Pym-Nixsons injured himself while mixing substances and creating three small explosions, neighbours had heard the loud bangs.

There was no evidence which indicated that Pym-Nixsons was creating explosive material for any malign purpose, or had any intention to make an improvised explosive device.

Pym-Nixson was arrested and his property searched by officers who found kilos of substances, when mixed, are known to create explosive materials.

He admitted to two offences under the Explosives Substances Act in November 2021 and was jailed for three years and seven months at Southward Crown Court on Tuesday April 5.

Commander Richard Smith, who leads the Counter Terrorism Command, said: "Pym-Nixson experimented with highly dangerous chemicals in uncontrolled conditions. His reckless actions put himself and others at risk, and could easily have resulted in a serious fire or explosion.

"This case further highlights how important it is for the public to report suspicious behaviour to police, so we can keep the public safe. We would urge anyone with concerns about anyone in their neighbourhood who they believe is committing crime to call police straight away – we will act."

The investigation was led by the Met's Counter Terrorism Command, following an initial review of the circumstances using the unit's specialist expertise.
