4 held off Madagascar after double murder

Police investigating the double murder of two French volunteers on an island off Madagascar have arrested four suspects.

Authorities arrested the four people, who were at the same nightclub as the two victims on Sunday, but have not yet established a firm link to the murders.

There is "no doubt" the two volunteers were murdered, police said. "We just need to determine a motive."

The bodies of the two French citizens, a man and a woman aged in their 20s, were found Sunday on a beach on the resort island of Sainte Marie with head injuries.

They had been volunteering at Cetamada, a local environmental non-profit organisation working to protect ocean mammals.

According to authorities on Sainte Marie, an island famous for eco-tourism, it is the first time French citizens have been murdered there.

In 2012, a French couple was found dead on a beach in southern Madagascar.

A year later, two Europeans were attacked and killed by a mob on the northwest island of Nosy Be, suspected of involvement in the death of an eight-year-old local boy.
