Officials say police in Cambodia have arrested the leader of the country's main opposition party in a late night raid.

Monovithya Kem, daughter of opposition chief Kem Sokha, says that more than 100 people raided his home and took him away in handcuffs early Sunday.

It was not immediately clear why the arrest took place.

Monovithya, who is also a member of the Cambodia National Rescue Party, says police did not have a warrant for her father's arrest.
