Two people who climbed gantries on the M25 have been arrested, as the motorway is disrupted for a fourth day.
Essex Police said it detained a woman at about 07:10 GMT on the clockwise carriageway about 1.5 miles (2.4km) before junction 28 for the A12.
Surrey Police made one arrest and one person was removed from a gantry at junction eight for Reigate.
National Highways said there were “multiple police-led incidents” on the M25 this morning.
One lane of the M25 was closed for a short time but all lanes between junctions 28 and 29 for the A127 are now open.
