Thanks for the link, Baldric. This makes sense now after reading the bit that says:
Aftermath[edit]
It has often been reported that after four days of news coverage British authorities issued a D-Notice, requesting that such reporting be discontinued for reasons of national security and the story disappear from newspapers. It is claimed by national newspapers in recent years, that some of the security boxes contained embarrassing or nationally sensitive material[2][5] and that the purpose of the request was to protect a prominent member of the British Royal Family.[2][6] Rowlands, the aforementioned ham radio operator, claims that the police attempted to prevent him from talking to the press by means of the D-Notice, which he felt was an attempt to hide police incompetence.[7] He also claims that police threatened to prosecute him for listening to an unlicensed radio station.[7] An investigation some years later showed that a request had never been made to the D-Notice committee at that time.[8] Furthermore, a D-Notice has no legal status, being a mere request and not a legally enforceable order. The Times newspaper was still reporting about the case over two months later.[9]
Other recent reports suggest that the identity of the criminals and their sentences have never been revealed.[2] However, The Times (amongst other newspapers) reported in January 1973 that four men had been convicted of the robbery at a trial at the Old Bailey. Three of these men were named as: Anthony Gavin, 38, a photographer from Dalston; Thomas Stephens, 35, a car dealer from Islington; and Reginald Tucker, 37, a company director from Hackney, who all pleaded guilty and who each received twelve years imprisonment. The fourth man, Benjamin Wolfe, 66, a fancy goods dealer from East Dulwich, pleaded not guilty but was subsequently convicted and received eight years. Wolfe had signed the lease on the shop used by the robbers.[3][10] Two other men accused of handling banknotes from the robbery were acquitted.[10] According to one press report, the police believed that the mastermind of the crime was another London car dealer who was never apprehended.[11] Thomas Stephens and Reg Tucker had sentences reduced to eight years on appeal.
