AN investigation to determine the cause of a major blaze on a bus in Bradford city centre is ongoing, fire service officials have confirmed.

It is nearly two weeks since the First bus blaze in Broadway sent plumes of thick black smoke billowing into the air.

Fire crews from Bradford and Shipley were called to the scene shortly after 3pm on October 9.

There were no passengers on board and no injuries were reported.

The driver of the bus only left the vehicle after he was alerted to smoke coming from a window on the top deck by a queueing passenger.

At the start of this week, the Telegraph & Argus asked West Yorkshire Fire and Rescue Service (WYFRS) if it had carried out an investigation into the blaze and, if so, what the outcome was.

A WYFRS spokesperson said on Monday its investigators attended the incident to determine the cause of the incident but added "no further information is available at this time".

They did not reveal the status of the investigation at the start of this week.

After further questioning by the T&A on behalf of the public, the spokesperson confirmed that the investigation is still ongoing.

They said there was "no indication" when the investigation would be completed.

A spokesperson for West Yorkshire Police said there was nothing to suggest the fire was suspicious.

A spokesperson for First Bradford said last week following the blaze: "One of our buses on the 607 service was involved in a fire incident on the upper deck.

"The bus was situated at Broadway during a changeover.

"There were no passengers on board and our driver acted calmly and professionally in alerting the emergency services who attended the scene and extinguished the fire."

The spokesperson added: "We do not know what caused the fire and will assist the investigation including a review of CCTV footage."

First said earlier this week it still did not know what caused the blaze.

On the day, firefighters were met with a scene described like that from a TV show, according to one woman who was working in a nearby building.

She raised concerns about the reaction of people to the fire, who seemed "completely oblivious to the dangers, more bothered about videos", while she was focused on getting people safe amid worries the bus could blow or the blaze could spread to neighbouring buildings.
