Last week Winchmore Hill Safer Neighbourhoods Team warned that on Wednesday 19th August on Firs Lane N21 people claiming to be from Thames Water had been going to addresses saying they want to inspect the manholes on in their gardens. They wanted to check the sewers there. They were in a Thames Water van and had high visibility jackets on but did not have any ID. Thames Water were called by the informant and they said there were no open or closed jobs in the area. They had no reference numbers they could leave the informant. Males were looking inside the informants house and asking how the bi-fold doors open.
