More than fifty officers swooped on the rubbish strewn camp at 4am after residents and businesses complained that they were making their lives a misery.
Police surrounded the camp of rough sleepers in the central reservation of the exclusive street, confiscating bedding and escorting them to a mobile police station.
In total 63 Roma travellers, around half of them women, were detained and quizzed by immigration enforcement officers from the Home Office.
In a new tactic they were offered free flights home on condition they left the country immediately.
Twenty people accepted the offer and were escorted in vans to Heathrow airport.
