A shocking video of a group of Teamsters racially abusing a Top Chef producer in 2014 surfaced on Wednesday as the men appeared in court.

Boston labor union Teamsters John Fidler, Daniel Redmond, Robert Cafarelli and Michael Ross were picketing outside a restaurant where the show was filming in the suburb of Milton when they made the comments.

The men claimed the production was taking work away from local people and are accused of demanding that workers from their union - the Brotherhood of Teamsters - be hired.

They are all now facing extortion charges for their allegedly unlawful attempts to secure the work.

During the encounter outside the restaurant, they hurled insults at producer Ellie Carbajal.

Redmond was filmed calling her a 'f***ing towel head' and a 'c**t'. Later, he added: 'At least I'm not a scab like you'.

Carbajal filmed their comments with her cell phone. It was used as evidence in court on Wednesday.

What it did not capture was the men allegedly 'swarming' star host Padma Lakshmi's car later and threatening to 'smash' her 'pretty little face in'.

When Lakshmi's car drove past, one of the men allegedly said: 'That’s the pretty one. We want to smash her face in.'

According to witnesses, John Fidler also reached into Lakshmi's chauffeured van, threatened to hit her and called her a 'f****** w****'.

Cafarelli later told Carbajal: 'You know what you are' while fellow union member Mark Harrington (right) filmed her. Harrington pleaded guilty to extortion last year but the others deny it

Prosecutors say she was left 'paralyzed' by fear.

Carbajal testified at the trial on Wednesday and said she was just as frightened.

'They got in my face. I was scared. I couldn’t believe they were doing this,' she said, according to Page Six.

'They were grown men,' she said. Lakshmi is expected to testify against the men on Thursday. All have pleaded not guilty to extortion.

Mark Harrington, another union member who was there, pleaded guilty to extortion last year.

Police officers were at the scene but did nothing to intervene, claiming the men were within their rights.

Afterwards, police received reports that the tires of several cars had been slashed at the scene.
