Co-director Paul Evans said company staff and directors were "horrified" by what his nephew had written.

"I'd like to make it clear that my nephew Richard is not involved in any way in this company, and all of us here were horrified by his despicable comments," he said.

Mr Evans is understood to work as a driver for haulage company Eddie Stobart.

A spokesman for the firm said: "We can confirm that we are aware of the reprehensible remarks made by Richard Gear Evans on social media.

"These remarks in no way reflect the view of Eddie Stobart Logistics and we have taken immediate action."

Markran Ali, 52, who collapsed and was receiving first aid when he was struck by the van, was pronounced dead at the scene

It remains unclear whether he died as a result of the impact.

Writing on Facebook his brother in law thanked well wishers for their support and urged people to keep Mr Ali in their prayers.

Meanwhile nine people who were injured in the attack remained in hospital last night, but police said none were now critical.
