Memories of 1972 blast.
A petrol bomb wrecked the Army Careers Officer (pictured) in a late-night attack on February 2, 1972.
There were fears that the attack was by supporters of Irish terror groups, as it came at the height of the troubles in Northern Ireland.
The only casualty of the attack was a firefighter, who suffered slight injuries when he and his colleagues fought the blaze.
A woman told the Examiner she had seen two youths outside the Army premises in Kirkgate at about 10pm.
One of them threw something at the front window and there was a bang as the building burst into flames.
Police sealed off the street throughout the night as detectives launched their investigation.
But the Army refused to be driven out of Huddersfield - where they have had a base for many years - and rebuilt the offices.
