A 21-year old woman has died a week after being hit by a tipper truck while riding her bike in the City of London.

The as-yet-unnamed woman from North London was crushed by the truck at the jnction of St Boltoph Street and Bevis Marks at 07:55 BST on Sunday 15 September, according to the BBC.

She was put on life support at the Royal London Hospital, a mile away from the scene, but City of London Police say she was taken off life support and died at 20:00 BST on Sunday.

Police are investigating, but say the driver of the truck has not been arested. 

Witness Rayhan Miah, who works in the nearby Tesco Express, told the Evening Standard: “It was a massive lorry. All I could see was the bike under the front of the lorry. There are always lorries going by because there’s quite a few stores around here.”

This incident is the fourth London cyclist fatality involving a tipper truck so far this year.

On April 7, Katherine Giles was killed when she was hit by a tipper truck in Westminster.

Philippine De Gerin-Ricard became London’s first Boris Bike fatality when she was crushed by a tipper truck at Aldgate on July 5.

Alan Neve died after being hit by a tipper truck on High Holborn on July 15.

After the death of Katherine Giles, London mayor Boris Johnson told ITV London News: “In future we are going to be stipulating that no HGV can enter London unless it meets cycle safety standards. One of the things that can be done is fitting of skirts to the sides of lorries and one of the big problems is that HGV drivers cannot see cyclists in the blind spot beside them.”

Those measures have still not been implemented, though details were announced earlier this month – tragically on the day Chiara Giacomini was killed by an HGV.

This latest cyclist fatality is the eighth this year in London. Six have involved trucks, Between 2008 and 2012, HGVs were involved in 53 per cent of London cyclist deaths despite making up only 4 per cent of the traffic.
