Police stepped up their presence on the bus network - to deal with the return of schoolchildren to the capital's transport system.

The back-to-school operation to deter antisocial behaviour in the first week of school meant monitoring bus routes in Hammersmith, Fulham and Westminster and lead to numerous arrests.

In Harrow Road, north Paddington, five people were arrested for public order offences and two for having outstanding warrants. While in Hammersmith, Fulham and Wandsworth, 20 people were arrested on the bus network for offences including possessing a blade and drugs charges.

The operations aimed to reassure the public, particularly young people, and deter youth antisocial behaviour on London's buses.

Chief Superintendent Joe Royle, from the Transport Operational Command Unit, said: "Antisocial behaviour creates an intimidating atmosphere for passengers and increases the fear of crime. This operation was about ensuring a safe travelling environment for young people travelling to and from school."
