OSAKA -- Osaka police have arrested a 19-year-old Chinese boy and obtained an arrest warrant for another Chinese on suspicion of robbery and murder in connection with the death of a 35-year-old prostitute inside a hotel here in December.

Police identified the fugitive suspect as Po Zhe, 21, a resident of Tokyo. The identity of the 19-year-old is being withheld because he is a minor. The two came to Japan in 2000 and were once students at Beppu University in Oita Prefecture.

The woman's body was found inside a hotel room in Kita Ward on Dec. 26. She had been bound with adhesive tape and died of multiple stab wounds.
