Reassurances into the continuation of Harrow’s “pleasant atmosphere” are being sought ahead of the Night Tube service coming into effect next month.

London Assembly member Shaun Bailey is concerned the service – which will run all night on Fridays and Saturdays – will be blighted by an increase in antisocial behaviour, bringing drunken revellers from the city centre to the outer areas, including Harrow.

Mr Bailey quizzed Mayor of London Sadiq Khan and Met police commissioner Sir Bernard Hogan-Howe at a London Assembly meeting on July 6.

“In many areas around these outer London Night Tube stations, such as Stanmore and Canons Park station, residents are accustomed to a quieter way of life, and many have chosen to live in these places because of this,” he said.

“Now we need to find out what will be done in Harrow to prevent a rise in antisocial behaviour.

“We are looking for reassurances from the Met that the areas surrounding the Night Tube stations will not be forcefully included into the 24-hour night time economy, and will maintain their safe, pleasant atmosphere.”

The Met has announced there will be an increased policing presence focused on highlighted Night Tube “red stations” – including Brixton, London Bridge, Vauxhall – most of them in the inner city.

However there has been no concrete plan laid out for the less central, presumably less problematic, stations.

The mayor has promised to publish a policing plan ahead of the serving starting on August 19.

Sir Hogan-Howe responded: “If you’re going to be patrolling 24-hour licencing areas and where the tube comes out at night, that produces its own challenges because it means they’ll either be dragged from neighbourhoods or response.”
