Six British bank staff members have been sacked after filming themselves staging a mock Isis-style execution during a team-building day out.
The HSBC workers were dressed in overalls and balaclavas at a go-karting centre when they staged a beheading scene, the Sun reported.
Footage posted online showed five of them laughing as a colleague in an orange jumpsuit, named as Saf Ahmed, knelt at their feet.
One clutched a coat hanger as a fake knife while another held Ahmed.

A worker apparently shouted "Allahu Akbar", a phrase often heard from Isis (Islamic State) in videos of them murdering hostages, before one was heard whooping.
The eight-second film was shot as the workers were on an away day at a Teamworks Karting track in Birmingham organised by the bank.
HSBC said those involved had been sacked for what it called an abhorrent video.
"We do not tolerate inappropriate behaviour," a spokesman said.
"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."
Kidnapped British aid workers Alan Henning and David Haines were both wearing orange jumpsuits when they were beheaded in Syria by Isis.
