The father of slain Tokyo bar hostess Lucie Blackman said Tuesday he has done nothing wrong amid claims that money has "gone missing" from the trust set up in his daughter's name.

A former employee of the Lucie Blackman Trust, who was fired in March, alleges that she was concerned about money contributed by members of the public disappearing even though Blackman told her not to worry about it.

Police are now investigating the alleged financial irregularities, which are thought to involve around $3,600.

"Following an inquiry from Hampshire Police, an internal investigation was conducted into the allegations of financial discrepancies," Blackman said in a released statement. "Following that, we have concluded there is no case to answer. We welcome any police inquiry to clarify this fact and to ensure the trust is cleared of these claims."
