The Apple Store in London's Covent Garden was reportedly raided by robbers on motorbikes in the early hours of Monday morning.

Rob Shoesmith, who is camping out outside the store in preparation for Friday's iPhone 4S launch, wrote that four motorbikes were used in the raid which took place at around 1.15am.

On his blog, Shoesmith wrote that he had been fast asleep when the raid happened but was woken by the sound of alarms. Police were on the scene soon afterwards.

The Guardian reports that two people - a 16-year-old male and 21-year-old male - have subsequently been arrested.

Detective Sergeant Nathan Tozer of Westminster CID said: "Although two men are in custody on suspicion of burglary, the inquiry continues and other persons are sought. It is essential that anyone who saw the smash and grab, or the suspects making off, contact us as soon as possible."

The exact value of good stolen isn't known, but iPads were thought to be among the raiders' haul.
