Six staff from Britain's biggest bank have been sacked after a video appeared online showing them taking part in a mock Islamic State style killing.
The footage is believed to have been taken during a team-building day and showed the workers dressed in overalls and balaclavas at a go-karting centre.
They were seen staging a beheading scene with five of them laughing and joking as a colleague in an orange jumpsuit knelt at their feet.
One clutched a coat hanger as a fake knife while another held the man in the jumpsuit by the shoulders.
According to The Sun newspaper a worker apparently shouted "Allahu Akbar", a phrase often heard by IS executioners in videos of them murdering hostages.
An HSBC spokesman said: "We do not tolerate inappropriate behaviour.
"As soon as The Sun brought this video to our attention we took the decision to sack the individuals involved.
"This is an abhorrent video and HSBC would like to apologise for any offence caused."
