The woman was found dead in the couple’s summer house in Norrtälje near Stockholm last weekend.

The man called the police and there were initially no suspicions of any foul play. But after conducting an autopsy on the body police have found cause to suspect the husband’s involvement, local newspaper Norrtelje Tidning reports.

“The body had a few too many injuries which require explanation,” inspector Jan-Erik Thölin at Norrtälje police told the newspaper.

Police were unwilling to specify the nature of the injuries found on the deceased woman’s body.

The man has since been taken in for questioning and the area around the summer house has been sealed off for a forensic examination.

On Monday the man was remanded into custody on suspicion of aggravated assault and manslaughter.
