More than 50 firefighters are currently at a warehouse fire in Northamptonshire.
Crews were called to the unit in Parsons Road on the Drayton Fields Industrial Estate just before midnight.
People living and working nearby are being told to keep their doors and windows shut.
Firefighters have made sure the fire hasn't spread to neighbouring buildings. However road closures are in place at the junctions of Parsons Road and Nasmyth Road and Lamport Drive and Newnham Drive.
Other businesses on the industrial estate are not affected by the fire and staff can still get to them.
Crews are expected to be there through the morning.
