PEACE protesters turned violent as they invaded an American nuclear bomber base.

Thirty demonstrators were arrested during ugly scenes at RAF Upper Heyford, near Bicester, in March 1984.

Hundreds of protesters from all over the country used wire cutters and their bare hands to help tear down the 10ft perimeter fence before streaming inside.

A dozen people ran onto the base and climbed aircraft shelters and a concrete tower, while the rest remained locked in a stand-off with police outside.

Demonstrators clashed with the force in events that looked to have taken police by surprise, with just a few MoD officers patrolling hundreds of yards of fencing at first.

The protest marked the first anniversary of the eviction of peace campers from a 30-acre extension to the base.
