Yobbish youngsters who spit, fight and push passengers in and around Hammersmith bus station could now face three months jail.
A dispersal zone will be enforced for six months from September 19 and gives the police power to disperse groups and forbid them from returning for at least 24 hours and issue a £2,500 fine.
Hammersmith and Fulham Police Inspector Dan Stobbart said: "Schoolchildren have been getting into arguments and bringing pit bull-type dogs into the bus station. They have been spitting from the top deck on to the lower decks of buses, pushing passengers and intimidating people. The problems occur at school turning out time, when children from 13 schools congregate in the bus station and use numerous different routes."
Insp Stobbart said there have been sporadic problems with pupils causing problems on the Broadway for 15 years.
This is the third time a six-month dispersal zone has been imposed in the area. The first was set up in September 2006 and the second a year later.
The new order means children aged under 16 can be removed from the Broadway between 9pm and 6pm unless they are under the control of a responsible person aged over 18. If they refuse to leave, they can be taken to their homes using reasonable force.
The dispersal zone includes Hammersmith Broadway shopping centre and the bus station. It is bordered by Queen Caroline Street, the south side of the Broadway, the west side of Butterwick and the north side of the A4 under Hammersmith flyover.
