Northamptonshire Fire and Rescue Service

A third teenager arrested after the retail park blaze is released without charge.

The fire service is providing home safety visits for people with dementia to ease relatives' minds.

A major incident was declared while 15 crews fought the inferno last week.

The fire service remains on site of an industrial blaze as locals are warned of ongoing effects.

The local council says it is talking to the property's owner about demolishing the damaged building.

The exercise involves 999 services, councils, health services and the military.

The fire and rescue service say the fire was out when they arrived but crews remain to damp down.

Explosive experts will carry out a controlled explosion of the device, says the fire service.
