ITV News can reveal the name of the haulage company being investigated by police over the deaths of four people who were struck by a lorry in Bath.

Grittenham Haulage Ltd based in Wiltshire refused to comment to us today when asked about the role of its truck in the tragedy.

We understand the company's owners have spent the day in talks with their solicitors at their haulage yard.

The firm is licensed to use five vehicles and is run by a man named Matthew Gordon. We were told by a family member that he had "nothing to say".

ITV News has also learned today that the police have asked the Driving & Vehicle Standards Agency to "assist with their investigation" and when we asked the DVSA specifically about Grittenham Haulage Ltd they said "while this is on-going we are unable to comment further".

The Traffic Commissioner confirmed to ITV News that Grittenham Haulage holds an operators licence but they say they are "unable to comment on individual cases, in the interests of justice".

Four people died when the lorry careered down Landsdowne Lane on Monday afternoon. Four-year-old Mitzi Rosanna Steady was the youngest victim.

Taxi driver, Stephen Vaughan was killed along with Phil Allen and an as yet unnamed 59 year old man when the truck crushed their car.

Police have confirmed that inquires are ongoing and are at an early stage. No arrests have been made.
