A BOMB blast sent a telephone kiosk door more than 60ft across a road in December 1983.
No one was injured by the blast on the corner of William Street and Marston Road, but police said it was not a prank.
The bomb rocked the area at 10.50pm, seconds after teenager John Horvath walked past the phone booth.

Mr Horvath, of Hugh Allen Crescent, Oxford, said: "I turned and saw the telephone box door fly across the road like a frisbee, scattering glass.
"Fifteen seconds earlier, I would have been in its path and killed. Smoke billowed out from the whole box, and it smelt weird."
Bomb experts from Brize Norton discovered another suspect package in a telephone kiosk outside the sub post office in Old Marston Road.
