A man has been arrested by counter-terrorism officers after “a number of suspicious substances” were found at a property in Bedfordshire.

The 31-year-old man, from Bedfordshire, was arrested on Tuesday on suspicion of possession of articles for terrorist purposes and remains in custody, the Metropolitan Police said.

He had previously been arrested on May 6 by Bedfordshire Police on suspicion of causing explosions likely to endanger life and possession of class A drugs, but was bailed before being re-arrested.

In a statement on Tuesday, the force said an ordnance disposal team had carried out a “controlled explosion” at the site on Hyde Road, Caddington, last week.

The investigation was taken over by the Met’s Counter Terrorism Command on Monday after continued searches at the residential address, the Met said.

The force added specialist officers continue to carry out searches at the address and have recovered a number of items and substances which are being dealt with and removed safely by specialist officers.

There is not believed to be any risk to local residents or the wider public.

The Met added it continues to work closely with colleagues from Bedfordshire Police and the Eastern Region Special Operations Unit as the investigation continues.
