Roads Policing Unit can confirm that a driver of a waste truck has been contacted following the death of a motorcyclist on the M27 earlier today.
The man was arrested on suspicion of causing death by careless driving and failing to stop.
The Roads Policing Unit said: "Closing a motorway is not something we take lightly. We are fully aware of the impact to the public and local businesses and we try to update the community regularly as to when it will be re-opened."
It is important to stress that we keeping an open mind about the collision until we have collated all the evidence and ruled out the possibility of any other vehicle being involved. That’s why it’s absolutely vital that anyone who witnessed the collision this morning or has any information that can help to get in touch. We are working very hard to re-open the motorway and hope to have all lanes running by half past one. For the sake of a proper investigation, we have to make sure we’ve covered every base and fulfilled our duty to the motorcyclist and his family.
