Facebook has borrowed $100m (£51m) as part of plans to expand its core infrastructure.

The money raised from Triplepoint Capital will be used to buy new servers for supporting the social network's increasing volume of users, according to Business Week.

The MySpace rival received 109.2 million visitors in March, according to traffic measurement site comScore – a rise of 240 per cent on the previous year.

The new investment adds to the $360m (£183.8m) Facebook has collected over the past six months. Microsoft paid $240m (£122.5m) for a 1.6 per cent stake in the company last October, while Hong Kong billionaire Li Ka-shing has now invested $120m (£61.3m) in the firm.

Last week Microsoft showed interest in expanding its stake in the social network, follwing the failure of its attempt to buy Yahoo.
