Police interrogated a 34-year-old unemployed man on Monday in connection with the disappearance in June of a company worker in Matsudo, Chiba Prefecture, officials said.

The man, a resident of Sumida Ward, Tokyo, whose name is being withheld, allegedly used bank cards belonging to Nobuyuki Murakami, a 50-year-old employee of a Tokyo stationery maker, to withdraw 1.3 million shortly after he went missing June 24, the officials said.

Police have found what appear to be bloodstains in Murakami's apartment in Matsudo. They plan to question the man to see if he has any knowledge of Murakami's whereabouts.

According to police, Murakami was last seen working overtime at his firm's office in Chuo Ward late June 24.

Murakami has since not responded to calls on his cellular phone, and his brother asked police to launch a search for him in early July.

Police said the man, who is technically being questioned on suspicion of theft, was caught on a security camera at a bank outlet in Tokyo using Murakami's two bank cards to withdraw all of his savings on June 26.

The man has so far told police he had known Murakami but denied that he withdrew the money from his bank accounts, the officials said.

Murakami lived alone and was scheduled to quit his company in mid-July.

He was scheduled to receive a retirement allowance of 20 million upon leaving the firm, according to police.

Investigators are quizzing Murakami's colleagues and friends to learn more about the circumstances surrounding his disappearance.
