The deadline for second round bids for Swedish Internet content provider Com Hem, backed by Carlyle Group, has been extended to allow a new bidder to examine the business. The news comes against a backdrop of booming buyout activity in the Nordic markets, with deal volumes reaching their highest level in four years.

Carlyle, which bought Com Hem alongside private equity firm Providence Equity Partners in 2006, has extended the bid deadline from July 7 to July 14 to allow a new bidder to take a more detailed look at the business, according to two people familiar with the situation.
