According to this article in the Telegraph, it would seem so.:

...evidence has now emerged suggesting that the well-guarded Sony DADC distribution centre was deliberately targeted by a professional gang, in a carefully planned raid, using the riots as a distraction.

Sources in the security industry disclosed that intruders first arrived wielding specialist cutting equipment and spent up to two hours dismantling a high security fence before breaking in.

It is claimed that they then summoned a fleet of vans and drove inside the premises, which are set back from the main focus of rioting in the area, before beginning to load up stock.

According to one source, security guards on site were effectively overwhelmed and unable to fend off the intruders, knowing that police were already stretched as anarchy gripped the capital.

The plot thickens… it did seem a bit unusual that a warehouse removed from the main riot areas went up in flames. Fans of independent music will be relieved to know, however, that Sony have set up a new distribution HQ to help avert bankrupycy by the labels effected by the fire.

Independent music distributor PIAS lose entire stock in London Riots

 
Sad news for fans of independent and alternative music - among the worst hit in last night’s large scale rioting in London were the very popular independent distributor PIAS (né Play It Again Sam) who look to have lost all their stock when the Sony warehouse in Enfield was burnt down. If you are a fan or collector of independent music you probably have a couple of releases brought to you by the company already - they distribute labels like Mute, Rough Trade, One Little Indian, Warp, Ninja Tune, Kompakt, Domino, FatCat, Soul Jazz, Rock Action, Chemikal Undergroud, and lots lots more. It’s estimated that PIAS handle around 30% of independent music in Europe.

PIAS have issued this statement via their website:

There was a fire last night at the SonyDADC warehouse which services the physical distribution for [PIAS] in the UK and Ireland. [PIAS] is working closely with SonyDADC who are implementing their emergency plans. [PIAS]‘s UK offices in London and all other areas of our business are unaffected.
More information will be communicated shortly to all our labels and partners.

A campaign has already begun to help the company, with suggestions that records or downloads from PIAS distributed labels be bought today in solidarity. A Paypal account is also being set up by Twitter user fionchadd (hashtag #labellove) for people to donate money through, which will be distributed among the labels affected by the loss of stock.
