A swan caused chaos on a motorway this morning when it ran among the traffic.

Drivers were forced to swerve to avoid the bird which was flapping around on the M23 near Pease Pottage, 400 yards north of junction 11.

Police sent a unit to chase the swan after receiving a dozen calls from worried drivers shortly after 9am.

The bird was thought to be a mute swan. It might have been injured and unable to fly away.
