A FATHER-of-three who died days after being struck by a pedal-powered "quadricycle" on New Brighton promenade was receiving treatment for cancer at this time of his death.

The 65-year-old man – who was hit by the four-wheeled pedal-powered vehicle on July 22 – died on Monday, although police say it is “too early to speculate” on the cause of death.

The pensioner, his wife and two boxer dogs, had been walking along the pedestrian promenade between Bubbles play centre and the Home and Bargain store at around 4.15pm last Tuesday when a blue quadricycle with four teenagers onboard came up behind them.

The youths – who were riding and acting anti-socially towards other people on the promenade – struck the pensioner with the vehicle, knocking him to the floor.

After stopping momentarily, the group of teenagers got back onto the quadricyle and left the scene in the direction of Fort Perch Rock.

The man - who bad been undergoing cancer treatment for some time - became poorly and was taken to Arrowe Park Hospital for treatment for his injuries that included swelling, bruising and head trauma.

He was discharged two days later but then sought further treatment at the Royal Liverpool University Hospital when his condition deteriorated on Friday.

He sadly died in that hospital in the early hours of Monday morning.

The result of a post mortem examination carried out today have been withheld by the pathologist pending the results of further tests.

The family of the 65-year-old man do not wish for him to be named in the media but it is known that he was a father of three sons and lived with his wife in West Derby, Liverpool.

His death is being treated by detectives as unexplained until a cause of death is known.

Investigations are underway into the full circumstances of both the incident on the promenade and the man’s subsequent death.

Police are keen to identify and trace the four people on board the quadricycle to establish their account of what happened and have released CCTV in an attempt to find them.

etective Inspector John Griffith from Wirral CID said: "We are pursuing a number of lines of enquiry to establish who these young men are as we believe they may have information that could assist our investigation.

"I would urge them to come forward and make themselves known to us so that we can go and speak to them and get their version of events. A number of passers-by went to this man's aid after he had been knocked over and I would also encourage those people to also contact the police as they may have information important to this case.

"At this stage it is too early to draw conclusions about the cause of the man’s death and it is unhelpful to speculate. We are treating it as an unexplained death until the results of a post mortem examination are known”
