Tokyo police searched a rental office in the capital Monday over a body abandonment case allegedly committed by the president of an information technology company, investigative sources said.

The 49-year-old suspect, Katsuya Mizuguchi, is believed to have used the rental office in the Shibadaimon district in Minato Ward as the office for his company, Linux Japan, after the body was allegedly taken out of the company¡¯s office in the Akasaka district in the same ward.

Police arrested Mizuguchi on Friday on suspicion of removing the body of a man believed to be an executive of Linux Japan from the office in Akasaka around Oct. 5 to 6 last year.

The body has not been found, and the executive in his 50s has been missing since September.

Monday¡¯s search, conducted in the presence of the suspect, started at around 10 a.m. and apparently ended in about two hours. Investigators loaded about five paper bags into their vehicles and left.

The suspect virtually lived in the rental office, the sources said.

Police have been searching around the Otarumitoge mountain pass along National Highway 20 in Sagamihara, Kanagawa Prefecture, where the body could have been abandoned.

The suspect bought blue tarps, air fresheners and a rope often used in construction sites around the time he allegedly abandoned the body, the sources said.

The rope was confiscated from the office, but there were no signs it had been used, they said.

The police found bloodstains in the Akasaka office and are suspecting that Mizuguchi committed murder.
