Business focused social network LinkedIn has cut its revenue forecasts for the second quarter, causing shares to fall sharply.

LinkedIn said a strong US dollar and the cost of purchasing online education platform Lynda were behind its decision to cut its forecast from $718 million to between $670m (£436m) and $675m in the three months to June.

It shares fell 25% in New York during extended trading.

Last month, LinkedIn announced that it would buy Lynda for $1.5bn.

The network's chief financial officer Steve Sordello said revenue contribution from the purchase of Lynda would "normalise" in the second half of 2016.

It comes as LinkedIn reported a loss of $43m in the first quarter, compared to a $13m loss in the same period last year.

However, it did see revenues jump 35% to $638m.
