A 28-year-old man has been arrested in Baltimore, Maryland, after he allegedly threw petrol on two of his colleagues and set them on fire.

The gruesome incident was allegedly the result of a workplace dispute.

Baltimore police said four colleagues were travelling in two cars when one of them ran out of fuel.

The four men pulled over and walked to a nearby petrol station. On the walk back, an argument broke out.

It was at that point, police claim, that Christopher Harrison Jr poured the petrol on two of the men and set them on fire.

Anthony Rodriguez, who also works for the company, told local news broadcaster WBAL that Harrison had a pre-existing dispute with one of the victims.

He said that on the walk back to the cars, they had "agreed to settle it" with a fight.

David Widener, who captured the incident on video, told them: "Nothing besides that was said, even leading up to the altercation. They both took their shirts off an appeared like they were going to fight."

After that, Rodriguez said: "He threw the gas on him and caught him on fire, and it just happened so quick."

Baltimore County police Corporal Shawn Vinson told WBAL that the two victims are in a critical condition in hospital. One suffered burns to 90 per cent of his body, the other, 60 per cent.

Police are in possession of the video of the incident and have said they will use it to help their investigation.

The police confirmed on Facebook that Harrison has now been charged with attempted first degree murder and first and second degree assasult.

Police have not identified the vicims, but one has been named online as David Campbell, in a GoFundMe fundraising page set up by his friends to raise money for his medical bills and to support him in the course of his recovery.
