One of the women dubbed an “Angel of Woolwich” for her role in calming down Lee Rigby’s two killers is now at the centre of an alleged racism row.

Ingrid Loyau-Kennett has again hit the headlines, this time for allegedly making racist claims in a Tesco pharmacy in Helston, in Cornwall.

Police are now investigating the claims on the 49-year-old, who was escorted from the building by security guards last Friday.

It is understood Tesco has been asked to hand over CCTV footage.

A spokesperson for Tesco said: “We are aware of an incident which took place at our Helston store on Friday. Colleagues at the store are helping the police with their inquiries.”

Ms Loyau-Kennett became a national treasure last May, after being among the first on the scene following the murder of Drummer Lee Rigby near his barracks.

The former cub scout leader had been visiting her children and was travelling to Victoria station en route to her Cornish home when her bus stopped at the scene of the Woolwich attack.

A trained first-aider, she went to check the soldier’s pulse before reasoning with his attackers.

Ms Loyau-Kennett was "threatened" with arrest in October last year after police were called to a disturbance at her home.
