The IRA team headed by
Eddie Butler drove slowly by the Portman Hotel in
Portman Square and fired approximately 20 rounds of 9mm ammunition into the hotel using a
Sten Submachine gun. Two hours later another IRA team drove by the
Carlton Tower Hotel located along
Cadogan Place,
Knightsbridge and fired into it with an
M1 carbine. Four people were injured in this attack, mainly from flying glass. At first people believed the attacks might have been motivated by anti-Semitism as both hotels were owned by Jewish businessmen. But police believed it to be the work of the Provisional IRA who carried out a similar shooting attack a month earlier on the 14 December 1974 against the
Churchill Hotel also in Portman Square in which three people were injured, including two American tourists and a Swedish businessman. like the one used to shoot at the Portman Hotel by the IRA, in January 1975 ==Aftermath==
