A MAN and a woman arrested by Counter Terrorism Police during an operation in Keighley in which potentially explosive material was found at a house have been bailed.

Searches are still continuing at the house today as enquiries continue.

Homes were evacuated following Sunday night's raid in Parkwood Street which also led to an Army’s Bomb Disposal Unit from Catterick being called in.

The man, 48, and woman, 29, were detained for questioning by officers from the North East Counter Terrorism Unit although a CTU spokesman said the incident was not now being treated as a terrorist-related matter.

Dawn Caswell, one of the people who had to leave their home on Parkwood Street, said she was first alerted by police at 11pm on Sunday.

"Some of us went to Keighley Leisure Centre, but there weren't that many people there because most went to stay with their families," she added.

"I didn't get back home till 4am. The police were still here - they would have been here all night.

"There were fire engines, police vans and police dogs.

"Everyone was just thinking 'what's going on?' I've lived in Parkwood Street for two years and normally it's quiet, I've never had any trouble."

Alex Goddard, who owns the nearby MAG Autos Garage, said: "Some people were speculating that some dangerous chemicals had been found, but by the time I got here at 6am it had all been sorted out."

Alan Barker, 42, who was evacuated from his own home with his partner and younger brother, said: "I was just gobsmacked when the police came round. It's the last kind of thing you'd expect.

"We were able to go round to a friend's house, so we didn't need to stay at the leisure centre.

"We're a few houses down from the house the police were going into, so weren't too worried about our own place.

"I was more worried about the people living next door to that house."

Keighley MP Kris Hopkins said: "I want to commend those officers from the Counter Terrorism Unit (CTU) involved in the intelligence-led arrest of two people in Keighley and the recovery of potentially hazardous material.

“I was informed of the operation and note that the matter is currently being treated as an isolated incident.

“I would like to appeal for calm and underline the CTU’s belief that there was no immediate threat to the well-being of local residents.

“I will continue to liaise closely with the relevant authorities whilst their investigations are ongoing.”

The CTU spokesman said: "We recognise that local people may have concerns as a result of this activity, and would like to reassure them that the arrests are intelligence led and not in response to any immediate threat.

"At this time, this is being treated as an isolated incident."
