Amazon has apologised after an error meant it showed a child a 15-rated film by mistake when they had tried to watch a PG movie.
The child's parent had paid to rent Diary of a Wimpy Kid from the firm's Prime Video service, but they soon realised it was incorrectly streaming Love & Other Drugs - which the British Board of Film Classification says contains "strong sex and sex references".
They complained to the media regulator Ofcom, which found Amazon in breach of its rules.
Amazon has apologised and fixed the issue, which it said was a result of the firm which licensed the films giving both the same code behind-the-scenes, when it is meant to be unique.
