More 7,000 laptops have reportedly been stolen from a warehouse in the US.

Thieves are said to have taken the equipment, worth up to US$4m (€3.5m), at gunpoint from a warehouse in Los Angeles.

The LA Times reports that five men pulled up at the warehouse late Friday night and ordered a security guard to open a gate.

The security guard was then tied up as the thieves loaded the laptops on to two trailers attached to two semi-trailer trucks.

The LAPD says its Auto Theft Section is now investigating the incident.
