Pierre Taki, a member of techno-pop duo Denki Groove and the voice of snowman Olaf in the Japanese-language version of the hit Disney movie "Frozen," was arrested Tuesday on suspicion of using cocaine, investigators said.

The 51-year-old, whose real name is Masanori Taki, has admitted to using a small quantity of cocaine in Tokyo and its vicinity earlier this week, according to a regional bureau of the health ministry's narcotics control department.

Authorities searched Taki's car and home in Tokyo's Setagaya Ward shortly after 6 p.m. on Tuesday based on several tip-offs. He was then arrested at around 11 p.m., after his urine sample tested positive for cocaine.

Early Wednesday morning, Taki was transferred to a police station in Koto Ward, where he is currently being detained. Investigators will check his cell phone to find out how he obtained the cocaine and how often he used it.

Possession or use of cocaine carries a prison sentence of up to seven years.

Taki — a native of Shizuoka Prefecture — is currently playing a supporting role in the NHK drama "Idaten" and has appeared in many film and TV productions.

Denki Groove, made up of Taki and Takkyu Ishino, has performed at a number of overseas music and dance festivals. This year, the duo took part in a tour to celebrate its 30th anniversary.
