From the South China Morning Post this week in: 1981
A bomb attack on the Hong Kong headquarters of the Shell Oil Company in Central resulted in an office messenger being injured and debris scattered across a substantial portion of the 16th floor of Shell House in Queen's Road.
Glass, wood splinters, chunks of wood and twisted metal from air-conditioning units showered the narrow lane where the main entrance to the building was located.
The force of the blast, travelling through vents and along ducts, also damaged Shell-occupied floors above and below. Hong Kong's business centre was cordoned off to all vehicle and pedestrian traffic.
Reports that a second bomb had been planted in one of the oil company's offices, installations or depots throughout the colony led to precautionary police searches. Nothing suspicious was found.
The Shell House explosion ripped through the top floors of the building soon after a hand-delivered note demanding HK$500,000 was received by the company. The bomb attack appeared to be the first case of terrorism directed against a foreign company based in Hong Kong.
