The emergency services in Friesland are looking for a 58-year-old man who failed to return home after going skating near Ryptsjerk, news agency ANP reports.

His family raised the alarm on Tuesday after the man failed to make contact.
Elsewhere at least three people have been pulled out of the water after the ice they were skating on gave way. In one case, a 65-year-old man was in the water for over an hour while rescue workers tried to bring him to safety, NOS tv said.
A number of people have also been treated for broken bones and other injuries after falling.
The Dutch skaters association is considering holding the first marathon race over natural ice in 12 years early next week. Seven potential locations have been identified but the ice must be at least 12 cm thick for the race to go ahead.
Swims cancelled
The cold weather has forced the cancellation of several New Year’s Day swims because ice is forming on lakes where the dips were supposed to take place. So far three of the 52 official swims have been cancelled, says main sponsor Unox. But as 35 swims are due to take place in fresh water, the number of cancellations is expected to rise.
The water temperature at the seaside resort of Scheveningen, where some 10,000 people are expected to swim, is put at six degrees Celsius.
