The attorney general has decided not to take action against a Muslim juror who allegedly listened to music during a murder trial.
Ruhela Khanom, in her 20s, was accused of hiding an MP3 player and earphones beneath an Islamic hijab or headscarf.
She was discharged from a murder trial jury at Blackfriars Crown Court.
The man on trial, Alan Wicks, was later jailed for life for murdering his wife. The attorney general"s office said there was insufficient evidence.
A statement from the office of the Attorney General, Baroness Scotland, said she had "considered carefully the papers in this matter, in particular the witness statements, and has concluded that there is insufficient evidence to provide a realistic prospect of proving beyond reasonable doubt any alleged contempt of court".
