An outraged customer demanded a 'confession' from a Subway worker, who he claims added bacon to his vegetarian sandwich - then tried to hide the evidence.

A clip posted on social media appears to show the member of staff being confronted by the shocked man.

The video, which was shared by UK rapper Mic Righteous, has been viewed thousands of times.

Angry customer Merdud Takalobighashi, 27, videoed the confrontation with a Subway worker over bacon he believes was put in his vegetarian sandwich

Musician Merdud Takalobighashi, 27, even went behind the counter so he could prove what happened.

He also claimed that the sandwich maker tried to hide the bacon behind his back.

He posted the clip alongside the words: 'I advise anyone that is Muslim, vegetarian or allergic to bacon to NEVER eat at subway near to Victoria coach station London.'

The video then shows him asking the staff member: 'Where did you put the bacon?'

Then he asks: 'It was in the cheese wasn't it?' to which the worker is seen responding: 'Yes, yes.'

A Subway spokesman said: 'Serving quality food that meets our customers' expectations is our top priority.

'With a number of different ingredient options on display, products may accidentally fall into the wrong container, as was the case in this incident.

'Should this occur, sandwich artists would be instructed to remove and replace the entire container. The store's employees have been trained in the correct procedure.'

It is unclear whether the bacon was inserted into the sandwich on purpose or by accident.
