Two people were arrested after "potentially explosive" chemicals were found at a house in West Yorkshire, police have said.

A 48-year-old man and 29-year-old woman were arrested at the address in Parkwood Street, Keighley on Sunday (4 September 2016).

"Potentially explosive material has been discovered during searches at the address," a North East Counter Terrorism Unit (CTU) spokeswoman said. Neighbouring homes were evacuated while police searched the address with residents only allowed to return in the early hours of Monday morning. The Army's Bomb Disposal Unit carried out a controlled explosion at the house.

"As a precautionary measure and in the interests of public safety, the immediate area was cordoned off and local residents evacuated while a thorough search was carried out and any potentially dangerous material was safely removed."

The spokeswoman said the arrets were "intelligence led" and were not in response to a particular threat. "Due to the nature of the materials recovered, the North East CTU is leading the investigation. However, this is not being treated as a counter terror incident at this time."

The people arrested on Sunday remain in custody while officers continue to search the house.
